A general structure for a time-domain model of the cochlea

This study presents an implementation of our basic ideas about a time-domain nonlinear model of the cochlea. The time-domain approach is considered necessary because it allows implementation of nonlinearity in general and of a proper temporal analysis of natural transient responses in particular. It should be considered a useful step towards a realistic biophysical model of the cochlea, which so far has been claimed by several colleagues, but in my opinion is still far from being accomplished. Several very different approaches are worked out separately, but convergence to a general solution remains to be achieved, as is also clear from a number of presentations at this conference. In this paper I will briefly mention some of the problems of current state of the art approaches. Unfortunately I will not be able to give all the solutions. I will focus on the general structure of a useful as well as promising model.
