| Outline of Final Research Achievements |
Tinnitus retraining therapy (TRT), which seeks to improve brain plasticity and
adaptation to tinnitus, has received a lot of attention in recent years as a treatment based on a neurophysiological model of tinnitus. The goal of TRT is to decrease the discomfort associated with tinnitus by retraining the brain to habituate to tinnitus. Sound therapy in TRT uses broad-band noise such as white noise, pink noise, and speech noise to remove tinnitus from conscious perception. However, the relationships between the effects of the therapy and the acoustical characteristics of the noise, such as the frequency spectrum, sound pressure level, and time-varying properties, have not yet been examined. Thus, this study was designed to investigate the effectiveness of different types of sounds for TRT.
