Using circuit analogies for analysis of cochlear models

PurposeDespite all the simplifications that are applied to make a cochlear model mathematically tractable, the time domain or frequency domain analysis of a cochlear model can still be a challenging problem. This paper presents a simple and effective approach to implementation of such models.MethodsA framework is developed by which a one-dimensional nonlinear cochlear model can be represented by equivalent circuits. The circuit then can be analysed in SPICE (Simulation Program with Integrated Circuit Emphasis).ResultsThe simulation results of the equivalent circuits are similar those achievable by other numerical methods.ConclusionsThe equivalent circuit representation of the model is easy to develop and implement in a circuit simulator such as SPICE. Moreover, the numerical methods which are used in SPICE are both fast and efficient for implementation of a cochlear model.
