An active one-dimensional cochlear model as a modefication of a passive model

Abstract

The passive transmission-line cochlear model which estimates Bekesy's data is developed for approximating Rhode's data on mechanical movements of the basilar membrance and the most recent observation by Sellick et al. It is shown that the model with parameter values altered represents Rhode's data well. But it is clear that the adjustment of parameter values for representing data by Sellick et al. is inevitably done. For this purpose, the characteristic impedance of the passive transmission-line model is amended so as to contain the coil. It is shown that the resulting frequency characteristic of the active transmission-line model provides the transfer function if an explicit form. The question of whether the energy is genereted in the circuit is also discussed
