In the Auditory Systems Laboratory, principles and methods of human factors engineering, ergonomics, and acoustics are applied to solve research problems concerning human hearing conservation, auditory information display, communications systems, product design, and general ergonomics. The facility is equipped to support industrial and community in-field investigations as well as controlled laboratory experimentation.
