Summary:
The cochlea is a good candidate for a high-performance Fourier analyzer used in engineering applications. Therefore, electronic circuit implementation of cochlear function is important. However, no high performance cochlear model is suitable for circuit implementation. Therefore, Kohda et al. proposed a simple cochlear model that can effectively reproduce the characteristics of the cochlea. The model is based on an ideal distributed constant circuit, and is referred to as a reflectionless transmission line model (cochlear reflectionless transmission line model). It can reproduce the physiological characteristics of the cochlea by adjusting circuit parameter values. In this paper, we describe an improved method for quantitative reproduction of cochlear characteristics using an optimization technique.
