A hearing aid has input AGC and output AGC using only one attack/release circuit and only one variable gain amplifier. An input AGC signal and an output AGC signal are summed and the summed signal, processed through the attack/release circuit, is used to control the gain of the variable gain amplifier.
Cette invention se rapporte à une prothèse auditive comportant une commande automatique de gain (CAG) en entrée et une commande automatique de gain (CAG) en sortie, et ne mettant en oeuvre qu'un seul circuit d'attaque/décharge et un seul amplificateur de gain. Un signal résultant de l'addition d'un signal CAG d'entrée et d'un signal CAG de sortie est traité par le circuit d'attaque/décharge et utilisé pour la commande du gain de l'amplificateur à gain variable.
