Simulation of a model of the basilar membrane in two dimensions for Spanish vowels

The inner ear has the cochlea as the principal element; this is a biological element in the form of a snail, within which the mechanical energy is converted into electrical energy. This process is realized by the inner ear cells on the basilar membrane. This membrane response is different for different frequencies of excitation; the result of this process is the human audition. This paper shows a simulation of a model in two dimensions of the basilar membrane and its characteristic response when excited by the tow first formants of Spanish vowels; these formants are obtained by an analysis by mixtures of Gaussians.
