Cochlear Mechanics: Analysis of the Transient Response.

Abstract

The hydroelastic model of the cochlea is used to analyze the transient response to a sound signal. Using the relatively high frequencies in the hearing range the equations are first reduced using viscous boundary layer theory. The reduced problem is solved by first applying the Fourier transform and then using the solution for a pure-tone signal. The response to a tone-pip is then studied and comparisons are made, when possible, with experiment. For example, the 'ringing' observed in the displacement of the basilar membrane is seen in the model and the theory agrees reasonably well with the neural latency measurements.
