Tinnitus retraining therapy (TRT) has become a popular treatment for the treatment of patients with tinnitus. This method involves the habituation of tinnitus perception using a low level sound generator and directive counseling. In this paper, we examined whether the most comfortable loudness level (MCL) and uncomfortable loudness level (UCL) changed after undergoing TRT. Nine patients (four males, five females) underwent TRT for 4-22 months (for an average of 12 months). The tinnitus handicap inventory (THI) score improved from 59.7 to 20.2, but neither the MCL nor the UCL showed any changes after TRT. In one patient where the UCL was particularly low prior to treatment, no changes were observed in either MCL or UCL after TRT.
