An apparatus for treating tinnitus involves generating a noise signal, by means of noise signal generator (10), to mask the ringing or buzzing in the ears caused by tinnitus and transposing the noise signal into the ultrasonic frequency range. As such, the masking signal effectively masks the tinnitus noise without interfering with the subject's perception of normal sounds such as human speech. In an alternative embodiment, human speech is transduced into electrical signals, transposed to the ultrasonic frequency range, and physically applied to the patient while tinnitus masking signals in the auditory range are applied to the patient.

Appareil de traitement d'acouphènes, consistant à produire un signal de bruit, à l'aide d'un générateur de signaux de bruit (10), afin de masquer le tintement ou le bourdonnement dans les oreilles provoqué par l'acouphène et à transposer le signal de bruit dans la gamme des fréquences ultrasoniques. De cette manière, le signal de masquage masque efficacement le bruit de l'acouphène sans interférer avec la perception de sons normaux, tels que la parole, par le sujet. Dans une variante d'exécution, la parole est transformée en signaux électriques, qui sont transposés dans la gamme des fréquences ultrasoniques et appliqués physiquement au patient, simultanément à des signaux de masquage d'acouphène dans la gamme des signaux audibles.
