The Auditory Physics Group works to solve fundamental problems in the mechanics and physiology of the peripheral auditory system. Through a combination of physiological measurements and theoretical modeling, we aim to understand the active, nonlinear signal processing performed by the inner ear while developing the power and precision of noninvasive probes of hearing function. Current interests of the group include cochlear nonlinearity and amplification, middle-ear mechanics and otoacoustic emissions.
