The Auditory Research Laboratory houses a double-wall sound-treated room and a hearing-protector test chamber for conducting hearing loss research. The quieted room is used for screening and/or evaluating human research subjects and conducting experiments where background sound levels must be kept at a minimum. The hearing protector test chamber is used to test the attenuation of hearing protectors and to research issues related to hearing protector usage and performance.
