Auditory Physiology Research

Our research addresses questions related to normal and diseased cochlear physiology. Our approach is to understand the origins of objective measurements that can be used in the clinic. If the cell types, spatial location, and contributing mechanisms can be understood, these objective measurements would have better differential diagnostic capabilities for sensorineural hearing loss.

Our research also addresses questions related to low-frequency hearing. Our approach uses a novel objective measure of low-frequency physiology – the Auditory Nerve Overlapped Waveform. As compared to the high-frequency cochlear base, less is known about the low-frequency cochlear apex because, in part, conventional electrophysiologic techniques perform adequately only at high-frequencies above 1 kHz or so. Understanding low-frequency hearing and hearing loss is important because the majority of speech sounds and many bothersome environmental background noises are of low frequency.
