Abstract
In order to have a better understanding of function of the cochlear implant, we first need to understand the cochlea's response at different input frequencies. As a result, in this study we chose a mechanical model of the traveling wave across the basilar membrane. The model was modified to incorporate the effect of OHCs (active cochlea) to be capable of explaining cochlear damages associated with damage or loss of outer hair cells. The simulated human cochlea is then used to model the insertion length of a sample cochlear implant on the human basilar membrane. The results are described and compared for both active and passive cochlea.
