Abstract :
A cascade digital scattering linear model of the cochlea, suitable for Kemp echo cochlea characterization, is developed. This model stems from a unidimensional transmission line model in which nonuniform and loss properties are included. Its lattice structure is obtained by rephrasing the model equations in terms of incident and reflected scattering waves. A characterization of the cochlea, through the estimation of the width, the stiffness, and the damping of the basilar membrane, is made with the model and the results compared to data available in the literature
