Two dimensional active nonlinear model of the cochlea

Togneri, R. and Attikiouzel, Y. (1991) Two dimensional active nonlinear model of the cochlea. Journal of Electrical and Electronics Engineering, Australia, 11 (3). pp. 164-171.


A nonlinear two-dimensional model of the basilar membrane structure solved by the finite difference technique is presented in this paper. In this model active feedback is used to provide sharp tuning and a saturating nonlinearity of the Outer Hair Cell (OHC) demonstrates suppression in the response at high intensity levels. A modified form of the Gaussian block elimination technique is used which leads to a significant reduction in the computations involved with a two-dimensional model.
