All ears

Foam wedges line the ceiling and walls to create an ultra-silent test chamber at Western University’s National Centre for Audiology. The Beltone Anechoic (“without echo”) chamber is designed to minimize external noise and absorb reflected sound above 125 Hz. The computer controlled turntable and vertical speaker array in the foreground simulate real-life soundscapes, such as crowds and street traffic, which allows, among other things, to test the three dimensional directional performance of hearing aids and assistive listening devices.
