CHAPTER
Overview chapter
Congratulations for choosing SoundPro DLX for your all-around sound level measurement needs. This instrument is an advanced sound level meter capable of producing a wide variety of point, averaged and integrated measurements of sound. Depending upon the SoundPro DLX model selected, many measurements can be broken into octave or third-octave components for an even finer analysis. Measurements can be viewed while they are occurring and in a summary display between measurement sessions. You can print from the summary display and transmit measurements results to a Quest application running on a personal computer for offline data analysis.
Instr ument char acteristics

Microphones
SoundPro DLX operates with interchangeable condenser or electret microphones designed for free field, random incidence and pressure measurements. To reduce distortions due to sound reflections, you can install an optional extender cable between the instrument and the preamplifier.
Multiple meters
SoundPro DLX is actually three meters in one. Each meter is separately configured, which enables you to make simultaneous measurements under different conditions. One of the meters can be set to perform octave and third-octave measurements of the sound signal.
Display
Both setup and measurements information is displayed on a touch-sensitive touchscreen. The displays are rich in detail and color, with full-featured capabilities that allow you to dynamically control what youre viewing in multiple ways. As a setup tool, you can quickly make selections from contextsensitive menus and view the settings in multiple displays. When viewing measurement results, you have a choice of viewing in dynamic, tabulated or historical formats, in some cases using panning and zooming options to obtain better resolution or observe long time trends.
Running studies
Each session consists of one or more studies performed with the same measurement settings. During a session, you can monitor accumulating results for that session. At your option, you can add additional information such as voice notes and drawings to a study when the study ends. Between sessions, you can view the final results in a Session Manager for sessions and studies residing in memory. Between sessions you can perform a wide variety of session editing, including renaming the session or any of its studies, edit much of the non-measurement information in the session and add additional voice notes and drawings.

2 OVERVIEW CHAPTER
Communications
Communications
SoundPro DLX is able to communicate with external devices in a variety of ways.
Ethernet ~ With an optional adapter, exchange information locally or through a computer network. USB ~ Connect by means of a USB adapter supplied with SoundPro DLX. Infrared ~ Print to a standalone or computer-supported printer via an infrared link. Wireless ~ With an optional adapter, exchange information point-to-point with your computer or through a wireless LAN. Web viewing ~ Remotely view SoundPro DLX displays live in a web browser.
Additional capabilities
You can periodically log data during studies. Data logging fills the accumulators only for the logging interval, then resets the accumulator to zero and repeats for the next logging interval. If your model is capable of obtaining filtered measurement results, you can log separately for each filter. You can secure your instrument against unauthorized use. If you shut down with security enabled, only a person who knows the security code will be able to use it. You can run studies automatically, either by triggering operation from a threshold or according to the calendar. Studies can be started, paused or the session in which they are running stopped. When stopping a session, you turn off the automatic triggering capability as well. You can compare filtered measurement results online with sound curves. Each sound curve shows the values previously measured over the audio spectrum. Sound curves help you detect changes during a study or differences between measurement results between studies.

An example is to move between displays that are alternatives in a group of displays.
Standby indicator
Not implemented at this time.
Charging indicator
With rechargeable battery packs installed and SoundPro DLX connected to an AC source, battery recharging is indicated by a blinking green light.
Powering-up
A power-up start occurs when power is provided to the instrument after it was completely unpowered. The unpowered condition exists for a new instrument, when the user removes all sources of power (batteries and AC) or after a reset operation. After completing a power-up start, you can switch the instrument into hibernation for quick startups. See Starting from hibernation on page 8. NOTE: When powering up a new instrument, install the rechargeable batteries packs provided, connect AC power and allow the batteries to fully charge before switching the instrument on. See Installing or changing batteries on page 102 for battery installation.
To perform a power-up start:
1. Provide battery power, external power or both. After a few seconds, the Quest globe logo appears and powering up proceeds automatically.
Battery power ~ See Installing or changing batteries on page 102 for installation instructions. When both batteries are installed and external power supply is provided, the instrument runs on external power. External power ~ Connect the external power supply. For information, see Power jack on page 4.
2. The powering up sequence takes at least a minute. When it is finished, the Security Logon display appears (Figure 24).
8 GETTING STARTED
Starting from hibernation
Figure 24
Security Logon display
NOTE: Logon security exists by default. You can disable it and change the logon code after successfully logging on (Security Settings on page 94). 3. Tap the security code (factory default code is 1-2-3-4) 4. Tap Enter in the display. If you entered the correct code, the Sound Level Meter (SLM) display appears. See The SLM and RTA display groups on page 14 for an overview of the six monitoring displays, including the Sound Level Meter (SLM) display.
Starting from hibernation

When the instrument is on, press and hold for about five seconds to put the instrument into hibernation. The hibernation state is also called the power off state. While you are holding the key, a message appears in the display telling you how much time is left before the instrument powers off. If you release the key before the counter reaches zero, the instrument remains on. NOTE: If you attempt to power off during a study, a message with a counter appears telling you that the session will be paused (study ended) in two seconds. If you hold the key until that time expires, the session is paused and the standard power off message appears giving you three more seconds to decide if you want the power off to occur. In hibernation, the display is turned off to conserve power consumption, and all but (the On/Off/Backlight key) is inactive. Sufficient power is provided by the main batteries or external power source, however, to preserve all the software initializations that were performed during the powering on operation. A restart from hibernation is therefore much faster than a restart from an unpowered condition.
GETTING STARTED 9
Software reset
Software reset
If your instrument ever appears to be operating abnormally, you should remove all operating power to return it to an unpowered condition. You can do that with either a software or a hardware reset. Try the software reset first. If that doesnt correct the problem, see Hardware reset on page 104.
To do a soft reset:
1. Using three fingers, simultaneously press the Up/Down/Right navigation keys on the front panel. 2. Hold the keys depressed for several seconds until the display begins to break up. 3. Release the keys and wait. Powering up should begin after a short delay.
Customizing for your use

Once you have the instrument operating, youll probably want to customize it for your conditions and individual use. For example, you can set the time and date (Date and Time Settings on page 93), change speaker volume Battery, Sound, Display Settings on page 96) and specify a language (Meter Information on page 97). To get busy with measurements, you may want to choose a meter profile (Meter Profile Settings on page 89) to establish a favored measurement setup.

List box scrolling ~ List boxes show you only the current choice, but you can change that current choice by scrolling. Tap arrows in the list box field to scroll through the choices. You cant use keys to scroll in a list box (not a wraparound list). Screen scrolling ~ When the amount of information in a display exceeds screen size, a scroll bar appears depending upon the excess. When the excess is left to right, a horizontal scroll bar appears. When the excess is top to bottom, a vertical scroll bar appears. Tap a scroll bar arrow to move the display in that direction. Tap and hold for continuous scrolling. You can also tap, hold and drag the Scroll Bar.
T he SLM and RTA display g r oups

After successfully completing the power-on procedure, the first display you will see is the Sound Level Meter display (SLM display). This display is one of three displays in the SLM Group. This group, and the closely corresponding Real Time Analysis Group (RTA Group) are shown in Figure 33.
SLM Group
The sound detected by the microphone can contain sound frequency components that vary over a relatively wide spectrum, depending upon the microphone type (Microphones on page 139). In general, displays in the SLM Group present measurements of that sound signal for the entire audio spectrum (broadband) without regard to variations among the frequency components. The SLM display in the SLM Group shows results for three measurements on all three meters at once. The SLM Tabular display shows you real-time tabulations of a large set of measurements, meter by meter. The SLM History display charts the last 30 seconds of measurements you select, meter by meter. Detailed information about the features and functions in these displays is given in Chapter 4, SLM display group.
RTA Group
The three displays of the RTA Group show results for one of the three Meter 1 measurements. If youre running broadband studies youll see broadband results in the RTA displays. If youre running filtered studies, however, youll see both broadband and filtered results in the RTA displays. The RTA Group contains the RTA display, the RTA Tabular display and the RTA History display that in many ways each correspond to the similarly named displays in the SLM Group. Detailed information about the features and functions in these displays is given in Chapter 5, RTA display group.
Navigational similarities
Both groups are available as separate selections from the Main Menu. After selecting, you can move between the displays of each of the groups in analogous ways. These navigational similarities are illustrated in Figure 33.

Infor mation and contr ol ar ea

The bottom portion of all displays in the SLM and RTA groups is an information and control area that contains a Navigation Panel, a Status Bar and the displays Title Bar (Figure 34). The Title Bar is a feature of all SoundPro DLX displays. Most displays contain the Navigation Panel, but only those displays that are directly associated with controlling measurements contain the Status Bar.
Navigation Panel Status Bar Title Bar Figure 34 Status panels in the SLM display
Navigation Panel
The icons in this panel are arranged in three clusters that are separated by short vertical bars. Within each cluster are touch-sensitive icons that look like the physical navigation keys. Associated with the key icons in each cluster are function icons. The key icons in a cluster are all touch-sensitive. Tapping a key icon executes the associated function in that cluster. In addition, pressing the actual keys that look like the key icons executes the same function. Table 32 explains most of those functions.

Status Bar
Alternate functions
The functions icons that appear in the Navigation Panel frequently differ between displays. Some displays lack function icons for some navigation keys. Others have multiple functions for those keys. When multiple functions exist, you need to press (Alt f key) to change to the alternate functions for the display. Pressing again changes back to the original functions, which are known as the standard or default functions for the display. Thus, acts like a toggle between the standard and alternate functions and function assignments. Figure 35 identifies elements in the Navigation Legend of the SLM display for the displays standard and alternate functions. Standard Functions

Run Time Clock

The Run Time Clock shows the elapsed time for a study. When you press to start a study, the Run Time Clock immediately resets to zero, the default name for the study appears, then the clock appears in place of the studys name and shows for the duration of that study. During a study, the Run Time Clock steadily increments in hours, minutes and seconds. When no study is running, the Run Time Clock shows the final run time for the last study that ran.
Title Bar
All SoundPro DLX displays are named in a Title Bar that appears at the bottom of the display. The Title Bar also holds the Input Panel icon. For information about this icon and using the Input Panel, see Input Panel on page 20.
Setup displays
Most SoundPro DLX setup procedures are contained in two groups of displays Instrument Setup and Global Setupand each consists of many setup pages. Both displays are available as selections from the Main menu. Select the top icon shown at the right to enter Instrument Setup. Select the bottom icon shown at the right to enter Global Setup. The selection always takes you to the page in the display that you last visited. These setup displays have many common features. See Chapter 9, Global setup, for information about all Global Setup displays. Information about the five Instrument Setup displays is given in the following sections.

Zoom and pan

When you enter a display in which measurements are graphed, the scale on the y-axis is always set to the current Measurement Range. In some displays, however, you can alter this range by zooming and panning. Zooming means that you can magnify or shrink the range and display the result over the entire display. Panning means that you can shift the range up or down in the display, changing what remains visible.
Result of zooming and panning

Figure 38 illustrates zooming and panning in the Log History display. The display at the right in this figure is the zoomed and panned version of the original display at the left for the same data. Relative to the original display, the zoomed and panned display shows the following features.
The full-scale range has been decreased from 100 dB to 50 dB, which means that the zoomed display shows a magnified version of the original display. While keeping the Range Ceiling nearly constant (small change from 90 dB to 85 dB), the Range Base has been moved up from 10 dB to 35 dB so that all of the measurement data remains in view. The Execute key has changed its function, as indicated by the red X in the zoomed display. Press Execute to end zooming and panning.

CHAPTER
SLM display group
SoundPro DLX operates with three sound level meters, all making independent measurements at once. This chapter explains how to set up the meters and how to use the displays in the SLM group to view measurement results.
Sound Level Meter (SLM) displ ay

As explained under The SLM and RTA display groups on page 14, you can launch the SLM displayone of the displays of the SLM display groupfrom the Main Menu. Press to display the Main Menu, scroll to the icon shown at the right, then press . The SLM display appears (Figure 41). You can also select directly from the Main Menu by tapping the icon.

Meter panels
The distinguishing feature of the SLM display is the presence of three meter panels. Except for the Measurement Range parameter, each meter functions entirely separately from the other two and has its own setup controls and measurement displays. Meter 2 and Meter 3 are identical in appearance and function, but Meter 1 has one feature that the other two dont havethe filtering controls. These filtering controls are located on a tab just above Meter 1 in the SLM display. To learn about using setting the filtering parameters, see Filtered analysis on page 28.

Common meter panel characteristics
Common meter panel characteristics

The characteristics that all three SoundPro DLX meters have in common are identified in Figure 42. Although the characteristics are common to all three meters, you can customize meter settings so that each meter makes measurements in different ways. Frequency Weighting Time Response Measurement 1 Meter Number
Measurement 2 Measurement 3
Range Base Figure 42
Maximum SPL SPL Activity Bar Shared meter panel characteristics
Range Ceiling
Parameters
The information shown in red in each meter panel are the current parametric settings for the meter. These settings control the operation of the meter and are user-selectable within limits. See Changing settings in SLM displays on page 27 for information about making changes. The setup parameters and the options available are specified below. For a detailed explanation of these parameters and their settings, see Appendix C, Measurements.
Frequency Weighting ~ Each meter can filter the incoming signal according to a frequency weighting curve that you select. The standardized weighting curves available are A, C, Z and C-A. A-weighting and C-weighting are industry standards that give greater weight to mid-range frequencies; Z-weighting means no weighting across the sound spectrum; C-A weighting means that both C-weighting and A-weighting are applied and the differences reported. Time Response ~ Each meter can react to the time-varying signal with a selectable time constant. The standardized time constants available are Fast, Impulse and Slow. Measurement Range ~ The Measurement Range is defined by the sum of the Range Base and the instruments dynamic range. To change the Range Base, see Changing meter parameters and measurements on page 28. The dynamic range is a fixed characteristic but depends upon the Analysis Type setting. If Analysis Type is set to Off, the dynamic range is 100 dB. If set to either 1/1 or 1/3, the dynamic range is reduced to 80 dB. For information about changing the Analysis Type, see Analysis Type menu on page 29.
SLM DISPLAY GROUP 27

Changing settings in SLM displays
Measurements
You can select from a list of many measurements for each of three positions in the meter panel. These measurements are identified in Figure 42 as Measurement 1, Measurement 2 and Measurement 3. The names are shown in light blue and the values are shown in black. For Measurement 1, the unit of measurement for Measurement 1 is also shown and colored blue. Any measurement can be selected for any of the three measurements of a meter. To select a different measurement, see Changing settings in SLM displays on page 27. For Meter 1, all three measurements report in accordance with the filter control settings (Filtered analysis on page 28). If the Analysis Type is set to OFF, all three Meter 1 measurements are broadband values. If filtering is chosen, all three measurements of Meter 1 are the filtered results for the selected filter.
SPL Activity Scale

In addition to showing the values of three selected measurements, each meter provides a visual indication of the current sound pressure level (SPL) on its SPL Activity Scale. All three SPL Activity Scales are calibrated to the same range, but the SPL activity indicated by each meter depends upon the meters setup. The numbers at the ends of the SPL Activity Scale specify the minimum (Range Base) and maximum (Range Ceiling) values of the calibrated range.
Activity Bar ~ The dark blue portion of the SPL Activity Scale represents the current SPL activity within the indicated range. If you do not see the Activity Bar or if it runs all the way across the Activity Scale, try changing the range setting. See To change the range setting: on page 28. Maximum SPL ~ When you see a light blue band at the right of the Activity Bar, that represents the maximum SPL in the preceding one-second interval.
Changing settings in SLM displays

The following instructions apply to all displays in the SLM display group. When you change something in one display, for example a meter or a meter parameter, the change is effective in all other SoundPro DLX displays in which that setting applies.

The three meters share the same Measurement Range, but the range can be translated up or down in 10 dB increments. For example, the Range Base can be increased from 30 dB to 50 dB, and when you do, the Range Ceiling for broadband measurements increases from 130 dB to 150 dB 1. Navigate to the SLM display. 2. The Navigation Bar must be showing the alternate functions (Alternate functions on page 17). 3. Press the Up/Down keys to translate the range. NOTE: The optimum range has been selected when the SPL activity bar (SPL Activity Scale on page 27) is operating near the center of its range. If the overload status bar icon turns black, increase the level range. If the under range status bar icon turns black, decrease the level-range (these icons are discussed under Status Bar on page 17.
Filtered analysis
SoundPro DLX always makes measurements over the applicable frequency range of the instrument (broadband analysis), but you can also filter measurements for display and accumulation purposes. Filtered analysis only applies to Meter 1. Depending upon your model, you can analyze the broadband signal using octave or third-octave filter bands.

Filtered analysis
When doing a filtered analysis, all measurements shown in the Meter 1 panel are either broadband or filtered values according to your choice. The tab at the top of the Meter 1 panel in the SPL display indicates the type of analysis and the selected filter, if any (Figure 43). Analysis Type setting Filter setting

SLM Histor y display

The SLM History display plots graphs of selected measurements for the last thirty seconds. The measurement curves update on a second-by-second basis, adding current data at the right, losing old data at the left, so that the curves appear to scroll automatically to the left. Unlike the logging history, this historical record is not saved. Also unlike logging, the results shown in the SLM History display pertain to the entire study, not just to incremental logging intervals. A particular advantage of the SLM History display is that you can use it to monitor the last thirty seconds of SPL values, whether you are running a study or not.
Navigating to the display

In general, you reach the SLM History display after first selecting the SLM display group from the Main Menu (Sound Level Meter (SLM) display on page 25). In the SLM display, press the Left key to go to the SLM History display. An example of this display is shown in Figure 45.

Move between the SLM Settings pages by tapping the Page Forward and Page Back buttons. Before making changes in parameter settings, select a meter by tapping its radio button. Most parameters are set when you select from a menu, but Integration Threshold and Exchange Rate are a little different. Also distinctive is the checkbox on page 2 that allows you to add additional study information during a session.
Integration Threshold
You can set an integration threshold but choose not to apply this parameter. Set the threshold by selecting from a menu just like all other SLM Settings parameters. To apply the threshold, select Enable. Clear Enable if you want the meter to inactivate this setting.
LN Source Meter
SoundPro DLX continually updates exceedance measurements at all 100 percentage points during studies, but you can choose four exceedance percentages for online viewing. These values, identified as Ln1, Ln2, Ln3 and Ln4 are derived from SPL measurements made by one of the three meters. Follow the instructions under Selecting settings from menus: on page 39 to set these percentage points. Tap one of the three radio buttons to specify the LN Source Meter for all exceedance measurements.

Exchange Rate
The Exchange Rate parameter and Integration Threshold settings determine the meaning of the time averaged SPL measurement. For an Exchange Rate of 3 dB and an inactivated Integration Threshold, the measurement is called the equivalent continuous SPL and is written as Leq. If, however, the Exchange Rate is set to some other value or if an Integration Threshold is used, the determination is a different average measurement and is written as Lavg. For information about setting these parameters, see Making changes in SLM Settings on page 37. SoundPro DLX tells you in the displays and in selection menus whether the time averaged SPL measurement is Leq or Lavg according to the Exchange Rate and Integration Threshold settings. If you change either Exchange Rate or Integration Threshold and that change results in a change in the meaning of the averaged SPL measurement, displays and menus are automatically updated with the new notation. Also, an advisory appears to inform you of the change. An example of the Leq/Lavg advisory is shown in Figure 412. In this example, the advisory tells you that the meaning of the time averaged SPL has changed from Leq to Lavg for Meter 1.
Figure 412
Leq/Lavg advisory
NOTE: The Leq/Lavg advisory remains on display until all references to Leq/Lavg for that meter are changed. If you had selected Leq or Lavg in Logging Settings for multiple filters, the advisory takes longer to clear.
Study information
Studies may be run with, or without, adding additional information to them during the session. Additional information includes voice notes and drawings, but you can also change the study name, identify the user and specify the location where the study was conducted. All of this information can be added or changed in the Session Manager after a session is stopped. See Study displays on page 79 for information about modifying studies in the Session Manager. If you would like to add or change study information during the session, select the Show study info screen in Instrument Setup. For additional information about this feature, see Adding information to a study on page 63. That check box is located on Page 2 of the SLM Settings pages.

Changing settings
The meter parameters that can be changed in SLM Settings are distributed over four pages in Instrument Setup. All of these settings are included in a profile that can be established as explained under Meter Profile Settings on page 89.
Page 1 ~ Criterion Level, Criterion Time and Projected Time. Page 2 ~ Upper Level Limit (ULL) and Peak Count Threshold (PCT). Page 3 ~ Point exceedance levels (L1, L2, L3, L4). Page 4 ~ Integration Threshold, Exchange Rate and Taktm Interval.
Selecting settings from menus:

RTA Hi stor y display

During a study, the RTA History display shows the last 15 seconds of results for one measurement plotted by time, frequency and level. Level is color-coded to provide a third dimension in the 2dimensional display. You can track SPL in the RTA History display because SPL represents a current measurement. But until you run a study you cannot track any other measurement in the display because those measurements depend upon what happened before.

In general, you reach the RTA History display after first selecting the RTA display group from the Main Menu (The SLM and RTA display groups on page 14). When viewing the RTA display, press the Left key to go to the RTA History display (Figure 54). Parameter Panel Level Legend

Sound curves
Sound cur ves

A sound curve is a line graph showing the value in each band at the moment it was captured. If you recorded a line curve during a session, the sound curve is saved for later use and immediately displayed in the RTA display. Sound curves are handy to show differences between measurements made at different times or under different conditions. Figure 57 shows a saved sound curve superimposed on an RTA display. With a sound curve present, the display exhibits several types of coloring.
Higher sound curve values ~ If sound curve values exceed current values, the area between the sound curve and current values is shown in white. Lower sound curve values ~ If current values exceed sound curve values, the sound curve values are shown in blue and the excess above sound curves are shown in red.

CHAPTER
Logging measurements
This chapter explains how to set the Logging Rate, select measurements to be logged and view logging results in real time.
Log ging Setup

The logging setup functions are provided on the Logging Settings page of Instrument Setup. You can change these settings at any time unless a session is open. When a session is open, the Instrument Setup icon on the Main Menu is unavailable. To display the Logging Settings page, press to display the Main Menu, then tap on the touchscreen to enter Instrument Setup. If you need help navigating to the Logging Settings page in Instrument Setup, see Navigating in Instrument Setup on page 35. The navigation icon in Instrument Setup for that page is shown at the right.
External factors that affect logging settings

In the Logging Settings display, you will have an opportunity to choose measurements to be logged. Those choices will, in some cases, depend upon what happens outside the Logging Settings display.
Before working in Logging settings. Set Analysis Type (Meter 1 only) ~ Set the Analysis Type before choosing logged measurements
in the Logged Settings display (Analysis Type menu on page 29). This is because changes you make to Analysis Type do not automatically update in the Logging Settings display. If, for example, you chose a filtered analysis, then chose measurements to log according to that analysis, then subsequently changed to a different Analysis Type, some of those previous logging selections might no longer be valid. You can always determine which measurements were actually logged by opening the Logged Measurements display in the Session Manager (Logged Measurements on page 80).
Meter Profile ~ A meter profile determines what measurements each of the three meters can make. You must select the meter profile before displaying Logging Setup to be able to select measurements available in that profile. For information about working with meter profiles, see Meter Profile Settings on page 89. Leq/Lavg measurements ~ You cannot log both Leq and Lavg on a meter at the same time, but you can log them simultaneously on different meters. These two measurements are alternatives for each meter based on your Exchange Rate and Integration Threshold settings in SLM Settings (Making changes in SLM Settings on page 37). Whenever you changes those settings, the Logging Settings display updates in accordance with the new settings.

Logging rate
The Logging Rate area has hour, minute, second and tenths of a second fields where you can set the logging rate by setting the logging interval (the rate is the inverse of the interval). Set the logging rate by selecting in those fields. The longest logging interval you can select is, essentially, 24 hours.
To set the logging rate:
1. Tap the arrow next to any field in the Log Rate panel. A menu appears. In the Logging Settings page in Figure 61, the seconds list is displayed. 2. Tap to select from the menu. The selection is displayed in the field. 3. Repeat steps 12 until you have the interval you want. NOTE: You may get an alert if you attempt to set the rate too high in relation to the total number of measurements previously selected (see Limits on page 53). When you tap OK to close the alert, your new logging rate will be ignored. Choose a lower logging rate or fewer measurements accordingly.
LOGGING MEASUREMENTS 53
Logging Measurements
Logging Measurements
Each meter has its own Logging List containing selected measurements to be logged. The Meter 1 Logging List can also contain filter specifications if the logging selections were made after a fulloctave or third-octave Analysis Type was previously selected.
Limits
You are not allowed to log a total of more than 104 measurements at a time. Also, you are not allowed to log a total of more than 12 measurements if you have the logging interval set to less than one second. These limits apply to measurements for all three meters combined, not just to measurements for each meter. If you attempt to exceed the limits, you will be alerted when attempting to add measurements to a logging list and your selection(s) will be ignored.
Adding measurements
Although you can log broadband measurements for any of the meters, you can also log filtered measurements for Meter 1 when its Analysis Type is set to either full or third-octave analysis. You can add as many filtered measurements to Meter 1s Logging List as you wish (up to the limits previously stated), including all of them at once with a single convenient selection.

Display characteristics
Display characteristics
At the moment you start a study, scaled data for selected measurements begin appearing at the right in the display. The values move to the left as time advances. When you stop the study, the final curves for those measurements are frozen in place. The X-axis in the Log History display is a count of the most recent logging events and is therefore indexed to time. If, for example, you have the logging rate set at five logging events per second (logging interval = 0.20 seconds), 60 on the x-axis represents a time interval of 12 seconds.
Selection Panel
The Selection Panel identifies which measurements are currently selected for display and shows the colors associated with each measurement curve. Because the measurements can be taken from any of the three meter Logging Lists, the Selection Panel identifies both measurement and the corresponding meter. For Meter 1 selections, in addition, the filter list selection(s) are shown.
Measurement scaling
Each logged measurement is scaled in the display, and you can read its amplitude from the scale at the left edge of the Display Range (Figure 62). This scale defaults to the existing Measurement Scale, but you can change it temporarily with the zoom and pan controls. To make the zoom and controls available, tap Zoom in the Navigation Panel. For information about these controls and how to use them, see Zoom and pan on page 21. You must cancel the zoom and pan controls before you can leave this display.
Selecting measurements to display

You can view a graph for up to four measurements. For each of the four choices, you can select any measurement from a Composite menu that contains all logging selections for all meters. The selections available on the Composite Menu are those measurements you selected for logging on the Logging Settings page of Instrument Setup (Logging Measurements on page 53).

CHAPTER
Using the instrument
This chapter provides an overview of the use of the instrument to collect data, from the initial setup of the microphone and hardware to the real time viewing of measurement results. You can also view results after theyre acquired, and for that information, see Chapter 8, Managing session data.
Positioning the instr ument

Tripod mounting
Whenever possible, the meter should be mounted on a tripod in a relatively open area to minimize reflections from your body or nearby large objects. Avoid placing against a wall or in a corner. If holding the instrument in your hand, keep your arm fully extended.
Preamplifier cable
If body reflections are a concern, connect the microphone to the preamplifier, then connect a preamplifier cable from the preamplifier to the instrument. Quest makes preamplifier cables in several lengths.
Microphone orientation
When using a random incidence microphone or pressure microphone, point it approximately 70 degrees away from the sound source. When using a free field microphone, point it directly toward the noise source.
Avoidance of contaminating fields

The instrument The SoundPro DLX is fully shielded and tested to work in fields up to 10 V/m, but contaminating fields can raise the SoundPro DLX noise floor. CAUTION: Handheld transceivers and cell phones in close proximity to the instrument can easily exceed 10 V/m. Working near high voltage lines or other transmitting antennae can lead to higher, erroneous measurements.
58 USING THE INSTRUMENT

Running studies
Running studies
Studies are run within sessions. You can record as many sessions, and as many studies within sessions, as there is room available in data memory. You can repetitively save measurements during studies by logging ones that you choose. You can do post-study verifications during session pauses that relate to the last calibration performed on the instrument.
Sessions
Collected data is organized by sessions. You cannot change measurement parameters during any part of a session. SoundPro DLX does not have a session open when you see on the Status Bar. All accumulators are reset to zero when a session is opened.
To run a session
1. Unplug all external cables and the charger. 2. Point the microphone toward the noise source.
Press

Pauses
A pause is an interval during a session when no study is running (no data being accumulated or recorded). The session is paused when you see on the Status Bar.
Logging
You can capture measurement values along the way in studies by logging. Logging occurs at a Logging Rate that you can set and for measurements you select (Chapter 6, Logging measurements). At each logging event, the values for that measurement are saved, and then the initial conditions for each logged measurement are reset to zero to prepare for measurements in the next logging interval.

In this example, icons that appear on the status bar during a session are used to indicate session status. Assuming that no session was open when Study 1 starts, pressing starts Study 1 and the session at once. When you press to stop Study 1, the session remains open but is in a pause state. You can continue to press to start and stop studies without stopping the session. During all the pauses, no data is either accumulated or logged, but SPL is continuously measured and displayed by the instrument during those intervals. You can stop the session by pressing during a session pause, as shown here, or you can stop it by pressing to stop the last study and session at once, thereby ignoring the terminating pause.
Calibr ations and veri fications

Use a Quest calibrator to calibrate the instrument outside sessions and to verify a calibration during pause periods within a session (post-study verification). If you dont have a Quest calibrator, see Miscellaneous on page 142 for specifications and ordering information. Perform these calibration and verification procedures in the Calibration Settings page, which is part of Instrument Setup. To display Calibration Settings, press to display the Main Menu, then tap on the touchscreen to enter Instrument Setup. Navigate in the displays Page Manager to the icon shown at the right. If you need help with this navigation, see Navigating in Instrument Setup on page 35.

Calibration Settings page
Calibration Settings page

The Calibration Settings page has data fields where you enter information about the calibrator and can view the instruments calibration history (Figure 72). You can also view the currently measured SPL. CAUTION: You should not attempt to change the setting for 200 V microphone polarization on this page except to match the needs of a different microphone (Microphone polarization on page 105). If you do try, a message will appear asking you to confirm.

Calibrator information
Quest makes two types of calibration kits: QC-10 and QC-20. The QC-10 has fixed output settings. The QC-20 has optional selections for both output level and frequency. Information on the output settings can be obtained from the calibrator label.
Level ~ The calibrator output level is in decibels. If you have a choice of output level, Quest recommends 114 dB for ordinary calibrations. Frequency ~ If you have a choice of output frequency, Quest recommends 1000 Hz for ordinary calibrations. Calibrator Serial Number ~ Read from the label.

Preparation
Calibration History list

Date/time entries identify both calibrations and post-study verifications.
For each successful calibration, an entry line appears in the Calibration History list that begins with the icon, , and is followed by the date and time of the calibration. For each successful post-study verification, an entry appears in the Calibration History list that begins with the icon, , and is followed by the date and time of the calibration. Each new entry is added at the top of the Calibration History list, and the rest are arranged in descending time order after that.
Double-tap a date/time entry in the Calibration History list to see the data retained for the event. Table 71 explains each of these data items. Table 71: Calibration History data Frequency ~ Value you entered into the Frequency field. Level ~ Value you entered into the Level field. Change ~ Difference in decibels between this calibration, or post-study verification, and the preceding one. Substantial deviations from zero when calibrating the same microphone might mean microphone degradation. Calibrator Serial Number. Polarization ~ Specifies whether the 200 VDC microphone polarization was turned on or off. Reference Range ~ The measurement range chosen by the instrument in response to the calibration signal.
Preparation
This procedure relates to calibration. When performing a post-study verification, you cannot change any of the calibrator settings.
To prepare and assemble:
1. Switch the calibrator to ON. If the LOBAT indicator is on, replace the calibrator batteries before using the calibrator. 2. If the calibrator has more than one output frequency, select 1000 Hz. 3. Press the calibrator adapter over the SoundPro DLX microphone until it fits evenly and snugly against the adapters retaining ridge. If you have more than one microphone, make sure you use the calibration adapter that is properly sized for it. 4. Slowly place the calibrator over the adapter, pressing the two together for an even and snug fit.

Performing a calibration
Performing a calibration
The instrument must be in a session stop state (session stop icon appearing in the Status Bar). Prepare the calibrator before starting the calibration procedure.
Calibration procedure:
1. Verify or set the value in the Level data box so that it agrees with the calibrators output level. 2. Verify or set the value in the Frequency data box so that it agrees with the calibrators output frequency. 3. When ready to calibrate, verify again that the calibrator is emitting sound. If not, switch the calibrator off and on again to restore the output, or replace calibrator batteries. 4. Press the Calibrate button. You will be notified on the touchscreen if the calibration was successful. If successful, the event is entered in the Calibration History list.
Performing a post-study verification

Prepare just as you did for a calibration. You must use the same calibrator, both to ensure consistency and because the calibrator information is taken from the last calibration for the instrument and you will not be allowed to change any of it. Also, the Calibrate button will be relabeled Verify.
Post-study verification procedure:
SoundPro DLX must be in a pause state (icon
showing on the Status Bar).
1. When ready to calibrate, verify that the calibrator is emitting sound. If not, switch the calibrator off and on again to restore the output, or replace calibrator batteries. 2. Press the Verify button. You will be notified on the touchscreen if the post-study verification was successful. If successful, the event is entered in the Calibration History list. 3. Disassemble to prepare for the next study.
Viewing the measured value

You will always be able to view the current SPL measurement from the Measured Value at the bottom of the Calibration Settings page. If the Measured Value exceeds the Range Ceiling, the Range Ceiling is displayed instead of the Measured Value and the up arrow at the right it is darkened. You can use the Measured Value to verify the measurement status during a calibration (or post-study verification) procedure. To do that, first verify that the measurement range includes the calibrators output level (Changing settings in SLM displays on page 27).
Calibrator detached ~ The ambient SPL is displayed as the Measured Value. Calibrator attached, ON, but prior to calibration ~ The instruments current accuracy in relation to an external calibrator is indicated as the difference between the Measured Value and the

calibrators output level. For example, if calibrators output is set to 114 dB and the Measured Value is 113.8 dB, the instrument is currently reading 0.2 dB low.
Calibrator attached, ON, after calibration ~ View the result of the calibration or post-study verification. The Measured Value should be within 0.1 dB of the calibrators output level.
Ad di ng infor mation to a study

SoundPro DLX automatically names sessions and studies for you. You can view and change these names in the Session Manager whenever no session is open. Optionally, you can provide identifying information for a study without waiting until the session is stopped. You can name the study, name the user, identify a location and provide comments. You can add a drawing, a voice note, or both, to the study at that time as well (Class/Type 1 models only). To add this information to a study during a session, select the Show study info screen check box in Instrument Setup before starting the session. See Making changes in SLM Settings on page 37.

Figure 76
Trigger Manager in threshold mode
Setting triggers
Click one of the radio buttons at the top of the Trigger Manager to select and configure either threshold or timed triggers. The threshold and timed triggers operate separately and require separate settings.
Threshold trigger mode

When you tap the threshold radio button, the threshold setup area shown in Figure 76 appears. This setup area provides for independent settings for two triggers. You can use triggers to start and stop studies in relation to measurements within a specified range. That range is determined by the two level settings for triggers 1 and 2. Both levels are referenced to the broadband sound pressure level measured by Meter 1.

Setting triggers
To configure each threshold trigger, tap the arrows at the edge of the selection boxes to select when a trigger event can occur and what action it causes. Other conditions must also be met for that action to take place, as explained under Putting triggered actions to work, below.
Condition ~ Select whether the SPL must be greater than (>) or less than (<) the threshold level set for this trigger. Action ~ Two action types are available: controlling a study or setting TTL output levels. To control a study, select a pause, start or stop action. If the control action is impossible, for example, trying to start a study when one is already running, the trigger event is ignored. There are two TTL channels available at the General Purpose Accessory connector, and the triggers can be used to set either of them high or low. Level ~ Select a value for the threshold level. You can choose any value in the range 0200 dB in 0.1 dB steps.
Timed trigger mode

The timed trigger starts and pauses studies repeatedly in the session according to date, time and repetition settings. For each setting, tap the arrow in the setting field to display options. For information about selecting dates and times, see Date and Time Settings on page 93.
Date ~ Select the date for the first timed study to occur. Tap the down arrow in the data box to display a calendar. In addition to selecting from the calendar, you can select the instruments current date by tapping the Today: line at the bottom of the calendar. Time ~ Select the time for the first timed study to occur. Tap the current setting for hours, minutes or seconds, then tap the up or down arrows to change (24-hour clock). For all but Occurs = Hourly, the time will be the same for every occurrence. Duration ~ Tap the current setting for hours, minutes or seconds, then tap the up or down arrows to change (Range is 0:0:0 up to 24:59:59). Occurs (Repetition Rate) ~ Tap the down arrows to display a list, then tap to select from the list. If you choose Weekly, the study will run on the same day each subsequent week. If you choose Weekdays, checkboxes for the days of the week will appear. Select those days of the week when you want studies to run.
Notes on timed trigger setup Starting times ~ For all settings of Occurs except Hourly, all timed studies will start at the same
time on subsequent days. For Occurs = Hourly, all timed studies will be started exactly one or more hours after the first study was started.
Long Duration ~ For Occurs = Hourly, setting Duration to longer than an hour will overlap one or more subsequent runs and cause them to be skipped.

Putting triggered actions to work
Putting triggered actions to work

You can do a trigger setup, but triggered control cant occur unless several conditions are met.
The trigger must be enabled. The instrument must be in a measurement status (threshold triggering only). Trigger conditions must be valid. The trigger action must be possible.
Enabling triggers
Enable threshold and timed triggers by selecting the Enable check boxes in the Trigger Manager. You must enable threshold and timed triggers separately. Threshold and timed triggers can be enabled at the same time if you wish. When you enable threshold triggering, both threshold triggers are enabled at the same time.
Disabling triggers
There are three ways to disable triggers.
Enable check box ~ Clear to disable threshold triggers and the time trigger separately. Triggered Stop (threshold trigger only) ~ If a threshold trigger requires a stop action and is valid, the study and session not only end but all triggering is disabled as well. Manual Stop ~ If you manually stop a session by pressing disable triggering at the same time. while triggering is enabled, you
Measurement status
Threshold triggering requires an SPL measurement, which only occurs when the instrument is processing a sound signal. Its not necessary for the instrument to be running a study or in a session for SPL measurement to occur. Timed triggering does not require the instrument to be actively measuring a sound signal. The instrument could be in a hibernation state when the timed trigger even occurs and still respond properly. If in hibernation, the instrument starts as usual, runs a study, and then shuts back down to a hibernation state when the triggered study ends.
Disabling triggers
You can disable threshold or timed triggers by clearing the Enable check box in the Trigger Manager. Clearing one type has no effect on the enable status of the other type, but disabling threshold triggers disables both threshold triggers at once.
Valid conditions
Triggering cant occur unless the conditions you established in Trigger Manager are valid. That means, for threshold triggering, that the action must be possible. For Timed Triggering, that means that no study is already underway when the time trigger occurs.

Viewing current session results
Trigger mode established

Even when triggering is enabled, it cant occur until the instrument is armed. Arming capability is available in any of display of the SPL or RTA display groups. To arm triggers after leaving the Trigger Manager, select the display and press . Arming wont start a study but will prepare the instrument to respond to the next trigger event. When either trigger is armed, the Trigger Icon shown at the right appears in the Status Bar. The icon blinks when a trigger is enabled but the instrument is unarmed. The Trigger Icon is steady when the instrument is armed. You can run start and pause studies in the usual way when the instrument is armed, but you wont be able to change settings in Instrument Setup or Global Setup. Nor will you be able to view sessions in Session Manager. You end arming by pressing .
Triggering interactions
Triggers can effect your studies as you run them manually. If a triggered pause or stop occurs while you are manually running a study, SoundPro DLX will comply as if you did it manually. Likewise, you can manually override a study that was triggered to start.

What is a meter profile?

A SoundPro DLX meter profile completely specifies the setup of the instrument to perform measurements, and controls some other features as well. All of the following are characteristics of a meter profile.
Profile name ~ All stored profiles have names, but profiles that are factory-supplied have reserved names that you may not use for your own profiles. Profile description ~ A stored profile can have a description. To see the profiles description, double-tap the profiles name in the Available Profiles list. Enabled measurements ~ You can enable measurements in the Meter Profile Settings page that affects the choices available on measurement lists in other displays, including the SLM displays, the RTA displays and the Logging Settings page. NOTE: Enabling measurements in a profile only restricts which measurements can be selected for viewing in the SLM and RTA displays. Those not enabled are still accumulated and included in the study results. The affect on logged measurements is different. Only measurements enabled in a profile will be available for logging.
SLM settings ~ All settings in the SLM display, both parameter settings and viewing settings (see Sound Level Meter (SLM) display on page 25).

CHAPTER
This chapter contains information on a variety of topics that may arise infrequently if at all.
Of the three component parts to a fully assembled SoundPro DLX instrument, only the microphone can be replaced by optional parts. No other preamplifier or instrument body is available. The standard microphone is an electret microphone, the Quest QE4936, but you can order the instrument with other types or obtain a different type later. The instrument is shipped with the correct microphone polarization for the microphone you ordered with it. If you change microphones after purchase, make sure youre using the correct microphone polarization setting. See the section below for that information. You can also order and install a cable between the microphone and the preamplifier for the purpose of reducing reflection errors. For information about replacement and optional parts, see Appendix D, Specifications.
T he back cover
The reset switch and main batteries are inside the back cover.
To remove the back cover:
1. Press the Button Latch firmly while sliding the cover toward the base of the instrument. The covers six edge pins will slide out of the mating slots (one pin and slot pair circled in Figure 101). 2. When the pins have cleared the slots, lift off the back cover and lay it aside.
To replace the back cover:
1. Line up the edge pins with the slots in the case. 2. Press down until the cover fits flush against the back of the instrument. You may need to squeeze the sides of the cover slightly to guide the pins into the slots. 3. Slide the cover toward the top of the instrument until the Button Latch re-engages, then release the button. The cover should fit tight all the way around.

Figure 101
Removing/replacing the back cover

SoundPro DLX is shipped with rechargeable Lithium-ion (Li-ion) batteries in two battery packs. Older SoundPro DLX models were shipped with rechargeable Nickel Metal Hydride batteries (NiMH) batteries in two battery packs. All models are also shipped with tubes into which standard AA alkaline cells can be placed and the tubes then installed in place of the rechargeable batteries. This section explains how to remove and install all three of these battery types.
Li-ion battery packs

Remove the back of the instrument as explained above. The batteries are installed in virtually the same way as the NiMH battery packs, explained under NiMH battery packs, below, except for battery pack orientation. First, note that there is a front and rear end of each battery pack. The cable connector is closer to the front end, and there are indentations along the ring at the front end that fit corresponding ribs in the battery well. Also, the case at the rear of the battery pack is designed so that it fits against a rear rib at the bottom of the battery well. Install the Li-ion battery packs straight down (no turning or twisting) with the front indentations sliding along the front ribs and the battery packs resting snug against the battery well. Plug in as explained under NiMH battery packs, below.
NiMH battery packs

Remove the back of the instrument as explained above. Each battery pack is connected to the instrument by a cable with a plug at the end. Insert the plug in the mating socket (Figure 102). The plug fits only one way and latches in place. Before replacing the cover, make sure the batteries are both oriented so that the battery wiring and wiring packs clear the cover (Figure 103).
MISCELLANEOUS 103
Figure 102
To install a NiMH battery pack:
Remove/install a NiMH battery pack
1. With the battery pack close to its slot in the case, orient the plug with the latch toward the inside of the instrument. 2. Press the battery plug into the case socket until the plug locks in place. 3. Lay the battery in the slot, rotating it as shown in Figure 103 so that the wiring pack will not stick up and interfere with the cover.
Figure 103 4. Repeat for the other battery. 5. Replace the back cover.
To remove a NiMH battery pack:

Hardware reset
2. Lift out one of the batteries without tugging on the battery cable. This will enable you to get a good grip on the plug. See Figure 102 for this and the following steps in the procedure. 3. Grab the plug between your forefinger and thumb, depressing the latch. 4. Pull the plug out of the socket and lift the battery out.
Alkaline batteries
Two tubes for alkaline battery cells are provided with the instrument. Install with reference to the drawing in Figure 104. NOTE: SoundPro DLXs built-in charging circuit works only through the socket provided for the rechargeable battery packs, not the end connectors used for the alkaline cells. Alkaline cells are not exposed to recharging current.
To install alkaline batteries:
1. Insert three AA alkaline cells in one of the battery tubes with all cells facing the same direction. 2. Lay the assembled tube in the cases battery slot with the positive battery end toward the instruments base. 3. Repeat these steps for the other tube. 4. Replace the back cover.

MISCELLANEOUS 105
Microphone polarization
1. Turn the instrument over and remove the back cover (see The back cover, above). 2. Locate the Reset Access hole in the case next to one of the battery slots (see Figure 105). 3. Find a nonconducting, blunt-tip rod that is small enough to fit through the hole. It needs to penetrate approximately 3/8". 4. Poke the rod straight through the Reset Access hole until it contacts the shaft of a push-button switch below. 5. Push the rod in, then release (no need to hold). You should hear a tiny click when operating the reset switch.
If successful, the SoundPro DLX display will start clearing, indicating that a reboot operation has started. If not successful, try again. Make sure that power to the instrument is available when performing a hardware reset.
6. Once the power-on sequence begins, replace the back cover and follow the procedure given under Powering-up on page 7.

Mi cr ophone polarization
The standard SoundPro DLX microphone for all models is an pre-polarized electret deviceit does not need external polarization. Other microphones available as options from Quest are condenser type microphones that do not carry their own charge and require an external polarization. For that reason the SoundPro DLX has a selection for microphone polarization. For information about microphone options, see Microphones on page 139.

Checking or changing microphone polarization
Checking or changing microphone polarization

Use the procedure below to verify, and if necessary change, the microphone polarization setting. SoundPro DLX is shipped with that setting disabled because its standard microphone is an electret type. If you should install a condenser microphone in place of a functioning electret microphone, simply enable the 200V potential setting. But when planning to install an electret microphone in place of a functioning condenser microphone, you must ensure that the setting is disabled before installing the microphone. Applying the 200V potential to an electret microphone can degrade or damage it. NOTE: The procedures below assume youre already familiar with the instrument, its controls and menus. If you need help with these procedures, see Chapter 2, Getting started. For information about working in the Calibration Settings page, see Calibrations and verifications on page 59.
Disabling the 200V polarization potential
1. Do not have the electret microphone installed when performing this procedure. You can have the preamplifier attached to the body without the microphone installed, or you can remove the preamplifier from the body. See Preamplifier on page 4 for assembly information. 2. Press 3. Press to switch the instrument on. and select Instrument Setup.
4. In Instrument Setup, tap in the Page Navigator to select the page represented by the icon shown at the right. This will open the Calibration Settings page. 5. For an electret microphone, clear the 200 V microphone polarization check box. 6. Install the microphone. You should see a normal SPL reading for the Measured Value at the bottom of the Calibration Settings page.

Glossary
This section contains an alphabetical listing of terms related to the analysis and measurement of sound by SoundPro DLX. Some of the terms are the measurements performed by SoundPro DLX, some terms are the user-adjustable parameters for those measurements, and other terms are names for nonnumerical settings for some of those parameters. Explanations for the SoundPro DLX measurements included in this list are all found in Appendix C, Measurements.
A
A Weighting parameter setting. See Weighting on page 120 for information about this and other Weighting settings.
Bandwidth
A range of frequencies defined by an upper band-edge frequency, f2, and a lower band-edge frequency, f1. The bandwidth is the difference between the two frequencies (f2 f1 Hz).
C
C-A
Center frequency
The filter identification you see in SoundPro DLX displays and menus that refer to the center frequencies of octave or third-octave passbands. Center frequencies can be exactly calculated, and are listed for the audio spectrum in ANSI and IEC specifications. The center frequencies cited in SoundPro DLX, however, are preferred values because theyre not quite exact but very close and more convenient for reference purposes.
CNEL
A SoundPro DLX measurement. See CNEL on page 125.
Criterion Level (CL)

The average sound level for a Criterion Time (generally 8 hours) that would result in a allowable dose of 100% for an individual exposed to that sound.
Criterion Time (CT)

The time over which the Criterion Level is established, generally eight hours.
114 GLOSSARY
Decibel (dB)
A dimensionless unit, commonly called the level in sound measurements, that compares two like quantities, such as powers or amplitudes, by forming a ratio of the two and taking the logarithm of the ratio. Decibel measurements express large differences with smaller numbers.
Dose
A SoundPro DLX measurement. See Dose on page 125.
Dynamic Range
The Dynamic Range of a sound pressure meter is the difference in decibels between the maximum SPL the instrument can measure accurately and the instruments noise floor. SoundPro DLXs Dynamic Range is 100 dB for broadband measurements and 80 dB for bandpass measurements.

Logging
In sound studies, the process of periodically saving measurements at fixed intervals during a study where each logged measurement is determined over the period of the logging interval.
Octave band
An octave band is a range of frequencies where the upper limiting frequency is twice the value of the lower limiting frequency. These limits, called band-edges, are the frequencies at which a filter transmits half as much power as the filter transmits at its center frequency.
Measurement
A numerical characteristic of the detected sound that is reported by SoundPro DLX. Measurements are determined by algorithms implemented in SoundPro DLX using user-adjustable parameters. Example of measurement include point measurements, time averaged measurements and time integrated measurements of SPL, along with times of occurrences of salient features in sound signals.
Measurement Range The decibel range within which the measurements are valid. The Measurement Range can be calculated by adding the instruments Dynamic Range to its Range Base or subtracting the Dynamic Range from the instruments Range Ceiling. Mntime

Projection time (Prt)

A SoundPro DLX parameter. This is the variable amount of time used to make a projected dose calculation (PDose) from an actual dose measurement.
Range Base
The minimum value of the Measurement Range. The Range Base is an adjustable parameter that can take on values between -10 dB and 80 dB when the Dynamic Range is 100 dB (broadband range) and values between -10 dB and 100 dB when the Dynamic Range is 80 dB (bandpass analysis range).
Range Ceiling
A SoundPro DLX display parameter. This is the maximum value of the Measurement Range. SoundPro DLX can measure up to a Range Ceiling of 180 dB.
Reference Sound Pressure

This reference pressure is defined for acoustic measurements to be 20 Pa (1 Pascal) when measured in air at 1000 Hz. This is approximately the threshold of normal hearing.
Response time
A SoundPro DLX parameter. This is an averaging characteristic that reduces the contributions of higher frequency components. Response time is commonly described by a time constant, which is a measurement of the time it takes for a system exposed to an abrupt input to rise or fall to the end condition. The SoundPro DLX response time parameter has three options: Slow, Fast and Impulse. For these, the associated time constants are 1.0 seconds, 0.125 seconds and 0.35 ms, respectively. Systems with a reduced response to higher frequencies will change by different amounts depending upon the length of time theyre exposed to an input. Figure B1 through Figure B3 below illustrate how SoundPro DLX responds to varying tone bursts for each of its response time options.

SPL
A SoundPro DLX measurement. See SPL on page 124.
Statistics
A SoundPro DLX measurement. During studies and sessions, SoundPro DLX continually determines how often sound at a particular level occurs in relation to the occurrence of sound at all levels. For this percentage distribution, continuous sound level measurements are grouped in 1 dB intervals. For example, sound measurements during a study might be spread over a 40 100 dB range, and during that measurement period the sound at 60 dB occurred 50% of the time.
Taktm
A SoundPro DLX measurement. See Taktm on page 125.
Taktm Interval
A SoundPro DLX parameter. This is the time interval over which Taktmaximal values are integrated, usually set to either three or five seconds. Taktmaximal is the maximum level (Lavg) encountered during the Taktm Interval, which is selectable in the SLM Settings display (Making changes in SLM Settings on page 37). Taktmaximal measurements are required by some countries noise regulations.
120 GLOSSARY
A Taktmaximal measurement calculates a higher average level for highly impulsive sounds than does an Leq measurement. Taktm is affected by the Exchange Rate and should be calculated with ER = 3 dB.
Third-octave band
A range of frequencies defined in ANSI S1.11. Each octave band contains three third-octave bands.

UR%
A SoundPro DLX measurement. See UR% on page 127.
Weighting
A SoundPro DLX parameter. The human ear does not respond to all sound in the same way. Higher and lower sound frequencies are attenuated so that normal hearing is confined to sound in the range of 20 Hz to 20,000 Hz (20 kHz). In addition, the frequency response depends to some degree on the sound pressure level as well. SoundPro DLX includes a weighting parameter that allows you to choose from among several weighting curves that provide varying corrections to the frequency components of the SPL measurementsA-weighting, C-weighting, Z-weighting or C-A weighting. A-weighting and C-weighting have been found over the years to best adjust for the hearing response at moderate and low sound levels, respectively. A-weighting is commonly used for general purpose sound measurements while C-weighting is applied when evaluating hearing protectors. When no adjustment for the hearing response is needed, investigators will often choose zero weighting (Z-weighting) which applies no adjustments in the measurement spectrum. C-A weighting is often used when performing community noise monitoring because it tends to enhance low frequency noise. The four figures below show the effect of weighting across the measurement spectrum for these four types of weighting. Relative response means the amount of attenuation at a particular frequency relative to the amount of weighting at 1 kHz. For each of these plots, the center curve is the weighting curve and the curves on either side of it represent tolerances specified in IEC standard 61672-1, March 2001, Sections 5.4 and 5.16.3.

Measurements
SoundPro DLX detects and analyzes sound using a wide variety of measurements. This section describes those measurements and, where applicable, gives calculation formulae. For definitions of terms and parameters, see Appendix B, Glossary. Some parameters are defined under Other formula parameters on page 127. For the purposes of formulae below, these are definitions: LS ~ Time-varying sound level, in decibels, that exceeds the Threshold Level. The response time of the measuring instrument is indicated by the second letter (Slow or Fast). RTIME ~ Run Time during which the measurement is made. TC ~ Time Constant for the exponential time weighting.
Time-weighted measur ements

Sound level measurements are reported after the sound signal is processed through an exponential time-weighting circuit with a user-selectable time constant.
Lmin
Minimum Level ~ Lowest SPL measured over a time interval.

Maximum Level ~ Highest SPL measured over a time interval.
LnX
Exceedance level ~ The level, in decibels, that was equaled or exceeded by the SPL a fixed percentage of time during an interval. For example, Ln60 = 40 dB means that the sound measured during an interval exceeded 40 dB more than 60% of the time. Exceedance measurements in SoundPro DLX are made at integer values of percentage. SoundPro DLX calculates exceedance levels for integral percentages throughout the 0100% range. You can select exceedance levels for online viewing at fixed percentages and at four custom percentages, which are designed as L1, L2, L3 and L4. To set custom exceedance levels, see Making changes in SLM Settings on page 37.
