The laboratory specializes on spatial hearing and the effects of assistive devices on hearing in 3-D environments. It allows researchers to study binaural hearing and the processing of signals in noise. This laboratory is also available to industry research. The word "anechoic" literally means "without echo" and to achieve this specific condition, the chamber is built of specialized material to minimize sound reflection and external noise. This facility supports a wide range of research projects requiring a highly-controlled sound field environment. Researchers in the fields of Music, Audiology, Hearing Science, and Engineering all make use of this facility [more].
The Reverberation Chamber simulates reverberant environments and is similarly equipped to the anechoic chamber, making protocols portable between environments. Significant reverberation as may be encountered in churches, airport terminals, gymnasia and large classrooms, reduces speech intelligibility and increases listening effort, especially for those with hearing impairment. While technologies are now available to effectively deal with interference from noise, we remain relatively unable to deal with reverberation which adds temporal interference to signals [more].
