Completely revised to reflect the research and technological advances of the last decade.
New chapters on directional microphones and the latest digital signal processing strategies …

In this thesis the growth dependency of head-related transfer functions and their resulting
parameters (interaural time and level differences) are analyzed as well as ear canal …

The IEC 60318-4 ear simulator is used to measure the insertion loss (IL) of earplugs in the
ear canal of an acoustical test fixture (ATF) and is designed to represent an average …

Acoustic impedances measured at the entrance of the ear canal provide information on both
the ear canal geometry and the terminating impedance at the eardrum, in principle …

BACKGROUND: There are different ways to analyze energy absorbance (EA) in the human
auditory system. In previous research, we developed a complete finite element model (FEM) …

The multimedia evolution has led to increased audio signal bandwidth in new generations of
smartphones, headsets, headphones, as well as hearing aids. Full audio bandwidth …

Acoustic test fixtures (ATFs) can be adopted to assess the sound attenuation of hearing
protectors (eg, earplugs and earmuffs) as they can facilitate measurements, and allow data …

Providing adequate relief from the occlusion effect while avoiding gain-limiting acoustic
feedback continues to be a major issue in hearing aid design and fitting. Traditionally fitting …

The human ear canal couples the external sound field to the eardrum and the solid parts of
the middle ear. Therefore, knowledge of the acoustic impedance of the human ear is widely …
