Abstract:
Nonlinear processes occurring in the peripheral auditory system are essential to our ability to hear small differences in 1) sound intensity, 2) time events, and 3) spectral features. Normal human audition is associated with the detection of vibratory events in the inner ear with an amplitude approximately of the diameter of a water molecule. Normal binaural hearing is also associated with discrimination of timing events with differences of 10 microseconds. Spectral discrimination can be modeled with a filter slope of 100 dB/ octave. Such amazing performance is dependent upon highly nonlinear processes in the peripheral ear. We will review nonlinear auditory processes and discover how EE has been essential to the understanding of hearing.
