Abstract

Un dispositif d'aide auditive (200) comprend au moins un microphone (210), un moyen de traitement du signal (220) et un transducteur de sortie (230). Le moyen de traitement du signal est conçu pour recevoir un signal d'entrée du microphone. Le moyen de traitement du signal est conçu pour appliquer un gain du dispositif d'aide auditive au signal d'entrée pour produire un signal de sortie produit par le transducteur de sortie, et le moyen de traitement du signal comprend un moyen de réglage du gain du dispositif d'aide auditive par un gain de transmission directe calculé du dispositif d'aide auditive.
