A Nonlinear Auditory Filterbank Controlled by Sub-band Instantaneous Frequency Estimates

Functional models of basilar membrane motion have a long tradition and a wide range of applications. They usually take as input the stapes vibration and provide the excitation pattern of the inner hair cells as an output. Even though the design of these models and the psychophysical data put into the model design are based on simple signals (e.g. sinusoids and twotone complexes), these models have the advantage to be also applicable to complex sounds (such as speech). Hence, they describe the degree to which we understand the response of the human peripheral auditory system to every-day sounds.
