In order to investigate the effect of the Meniere disease on a hearing sensitivity caused by endolympatic hydrops, we developed a three dimensional finite element model of the cochlea. The model has a tapered box shape, and tonotopical property of the basilar membrane was well described in the model. Fro the validation of the model, the air-conducted (AC) sound in a cochlea was simulated. Results show that the BM velocity was decreased at low frequency ranges in AC whereas the velocity was not changed at high frequency ranges, which were consistent with the previously published data. Furthermore, the effect of the Meniere disease on a bone-conducted (BC) hearing pathway was investigated through the simulation. Results show that there were insignificant effects on a BC hearing from the Meniere disease regardless of the input frequencies.
