Abstract

Ecouteur intra-auriculaire La présente invention concerne un écouteur intra-auriculaire (10) comportant, dans un boitier anatomique (14), un transducteur électro-acoustique (18) propre à diffuser un son et une unité (20) de pilotage du transducteur (18) propre à recevoir un signal à reproduire comportant un filtre d’égalisation appliqué au signal à reproduire, laquelle unité (20) est connectée à un microphone interne (30) de l’écouteur. L’unité (20) comporte en outre des moyens d’estimation d’un chemin secondaire acoustique et des moyens de définition et d’application en continu du filtre d’égalisation en fonction de l’estimation du chemin secondaire acoustique. L’écouteur comporte un microphone externe (32). Les moyens d’estimation du chemin secondaire sont propres à estimer le chemin secondaire acoustique en fonction également du signal sonore mesuré par le microphone externe (32).
