A three-dimensional nonlinear active cochlear model analyzed by the WKB-numeric method.

摘要: A physiologically based nonlinear active cochlear model is presented. The includes the three-dimensional viscous fluid effects, an orthotropic partition with dimensional and material property variation along its length, a feed-forward mechanism of organ Corti. hybrid asymptotic numerical method combined Fourier series expansions used to provide fast efficient iterative procedure for modeling simulation responses in cochlea. results chinchilla cochlea compare very well experimental measurements, capturing several features observed basilar membrane responses. These include compression response stimulus level, two-tone suppressions, generation harmonic distortion products.
