Electrical tinnitus control.

Abstract

A new method of electrical tinnitus control employs sine-wave frequencies, slowly varying between 0.2 and 20 kHz and modulating a 60 kHz carrier. The latter literally carries the audio-frequencies "under the skin" via external electrodes placed on both mastoids. Patients undergo exposure at home. The dosis increases from 1 h/day to maximally 5 h/day. Suppression is achieved in about 60% of selected patients. Once tinnitus is under control, usually after 3-5 sessions, exposure may be reduced.
