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 suc h as human speech. In an alternative embodiment, human speech is transduced in to 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.
