Tinnitus in 55 ears was treated with a custom made tinnitus suppressor which was designed to apply an alternative current to the cochlea of patients and the current level was in the range of 200-300μA. A well charge balanced stimulus waveforms, whose stimulus current density around the electrode is 1.25μC·cm-2·geom/phase, was used and it was shown from our treatment that no problem in patients was observed. Averaged loudness level (difference between tinnitus level and hearing level) of tinnitus before treatment was 15.7dB, while 8.4dB after treatment. More than 5dB of tinnitus level was improved in 30 of 55 ears treated with the device and in 5 ears tinnitus disappeared.
