Abstract

Auditory processing is one of the most complex and fundamental tasks in human psychophysiology. In the past 150 years researchers have tried to understand how sound and especially speech is processed in the human ear. Today, digital auditory filter models and nonlinear active silicon cochlea models are used to simulate cochlear sound processing. This article therefore aims at describing a simple algorithm to derive transfer functions coefficients for an auditory filterbank from tuning curves. Based on the model of the basilar membrane as a cascade of second order lowpass filters, the transfer functions are adopted to experimental data of tuning curves in the cochlea. With basic information on the shape of the travelling waves the presented algorithm is able to derive transfer function coefficients for an auditory filterbank. After the algorithm is explained this article shows how to use it in the presence of experimental data, and gives an application to a an operational amplifier filter circuit using active compensation.
