Cochlear Distortion Simulator V 1.1
Released October 17, 2003
Cochlear Distortion Simulation Program
Available for free download from this site
Introduction
Our group is interested in the changes of distortion in the cochlea
that result from endolymph volume disturbances such as endolymphatic hydrops.
One way that distortion is affected is through changes in operating point
of the cochlear transducer. This is similar to the situation where you push
your finger against a speaker cone that is playing a sound. If you push
hard enough, the sound will become distorted, especially at low frequencies.
This is because your finger stops the speaker cone moving in one direction,
so that it vibrates asymetrically and distorts the sound. Similarly in the
ear, an endolymph volume increase can push the organ of Corti towards scala
tympani, so that it vibrates asymetrically and distorts the incoming sound.
The simulation program allows the effect of operating point shifts on transduction
to be calculated. The program is intended for teaching and research applications.
