Study Summary
Millions of Americans suffer from tinnitus. However, there is no widely accepted treatment that has been shown to be effective in controlled investigations. The purpose of this study is to evaluate the effectiveness of Tinnitus Retraining Therapy (TRT). This study will investigate the contributions of counseling, the use of hearing aids and sound generators, and the importance of setting masking noise to a particular level. All groups will receive the same Counseling. In pilot studies we have developed a picture-based counseling protocol. The results of this study will determine if TRT is more effective than masking or counseling alone.
