Frequency sensitivity in mammalian hearing from a fundamental nonlinear physics model of the inner ear


Kanders, Karlis; Lorimer, Tom; Gomez, Florian; Stoop, Ruedi (2017). Frequency sensitivity in mammalian hearing from a fundamental nonlinear physics model of the inner ear. Scientific Reports, 7:9931.

Abstract

A dominant view holds that the outer and middle ear are the determining factors for the frequency dependence of mammalian hearing sensitivity, but this view has been challenged. In the ensuing debate, there has been a missing element regarding in what sense and to what degree the biophysics of the inner ear might contribute to this frequency dependence. Here, we show that a simple model of the inner ear based on fundamental physical principles, reproduces, alone, the experimentally observed frequency dependence of the hearing threshold. This provides direct cochlea modeling support of the possibility that the inner ear could have a substantial role in determining the frequency dependence of mammalian hearing.
