Purpose: Despite 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.
Methods: A 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).
Results: The simulation results of the equivalent circuits are similar those achievable by other numerical methods.
Conclusions: The 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.
