Cochlear Simulation 2.22

CochSim is an interactive PC program for demonstrating how the cochlea analyses sounds. With Cochsim you can put various signals into the cochlea and see a dynamic simulation of how the basilar membrane and excitation pattern responds to the sound. Cochlear Simulation is a dynamic simulation of the time and frequency analysis performed by the ear. Sound signals such as sinewaves, pulse trains, sawtooth waves and vowels can be fed into an auditory filterbank and the output monitored in a moving animated display. The program shows the vibration of the oval window and the basilar membrane, the haircell activity against filter frequency and time, and an average excitation pattern across the cochlea.
