Abstract

On décrit un modèle qui simule une analyse spectrale cochléaire (Fig. 3) et comporte une paire de réseaux coordonnés entièrement à base de lignes interconnectées par plusieurs coupleurs d'extrémités et donnant un traitement de signal bilatéral réparti non linéaire. L'un des réseaux ainsi que les coupleurs d'extrémités correspondent à l'organe de Corti qu'on trouve dans la cochlée et le deuxième réseau correspond à la membrane basilaire également placée dans la cochlée, de manière que ce modèle offre une ressemblance frappante en matière de structure avec les propriétés physiques de la cochlée elle-même. Avec un tel modèle, on simule des produits de distorsion et des émissions oto-acoustiques. On décrit aussi un modèle intermédiaire (Fig. 10) qui donne un traitement de signal bilatéral non linéaire et une amplification complémentaire d'onde directionnelle. L'invention met en ÷uvre ce modèle cochléaire à l'aide d'une technologie à électronique analogique qui s'accorde mieux avec la biophysique cellulaire de l'oreille humaine.
