Abstract

PURPOSE: To provide a reverberation time measuring device, in which both the voltage attenuated in accordance with the reverberation attenuating curve of a room and the voltage attenuated in accordance with the discharge curve determined by the CR time constant of a capacitor are impressed upon a differential amplifier so that the reverbration time may be measured correctly without any difference among indivudials.
