Abstract

La présente invention propose un appareil auditif avec microphone derrière l'oreille (1) qui ne sera pas placé dans le conduit auditif (5), qui permet aux faisceaux produits (9) de fournir une amplification passablement constante indépendante de la direction d'arrivée d'un signal acoustique émis à une fréquence préétablie (10) et qui assure cette directivité fréquentielle de façon à rétablir la fonction de transfert thermique de la personne.
