Abstract

In this paper, a three-dimensional passive spiral cochlear model which includes the oval window (OW), round window (RW), basilar membrane (BM) is established. Harmonic response analysis is then carried out. Results on the cochlear impedance, basilar membrane response and intracochlear pressure which contain the scala vestibule and scala tympani pressure are obtained. The satisfactory agreements between the model results and the experimental data in the literature prove the validity of the finite element (FE) model. Based on the FE model, the effect of fluid viscosity to the cochlear impedance and variation of the amplitude of the BM in a transverse direction at 12mm under normal forward sound stimulation and reverse RW stimulation have been discussed. The results suggest that the cochlear impedance is increased because of the fluid viscosity. In the meantime, compared with the simplified uncoiled model, the curvature of the spiral BM has a great effect on the amplitude in a transverse direction at high frequencies under different stimulations and the range of sense in frequency is expanded on account of the spiral geometrical characteristic.
