Our research addresses questions on normal and pathologic cochlear physiology. Our approach requires the development of novel electrophysiologic techniques. At present, we are using a new objective measure of low-frequency physiology. As compared to the cochlear base, less is known about the cochlear apex because, in part, conventional electrophysiologic techniques such as otoacoustic emissions and compound action potentials perform adequately only at high-frequencies above 1 kHz or so. Understanding low-frequency hearing and hearing loss is important because speech vowels and many bothersome environmental background noises are of low frequency.
