Abstract

L'appareil de correction auditive comprend deux microphones dirigés suivant des directions différentes et dont les sorties en audiofréquences sont appliquées à un circuit soustractif, la balance des entrées vers ce circuit pouvant etre commandée. Des filtres passe-bande commandés numériquement avec une possibilité de sélection de bande et de niveau d'amplification sont prévus dans l'appareil, de telle sorte que la réponse en fréquence de l'appareil puisse etre adaptée à l'utilisateur individuel.
