Tinnitus retraining therapy Tinnitus retraining therapy Tinnitus retraining therapy (TRT) is a form of habituation therapy designed to help people who suffer from tinnitus, a ringing, buzzing, hissing, or other sound in the ears when no external sound is present. Two key components of TRT directly follow from the neurophysiological model of tinnitus. One of these principles includes directive counseling aimed at reclassification of tinnitus to a category of neutral signals, while the other includes sound therapy which is aimed at weakening tinnitus related neuronal activity. The goal of TRT is management of tinnitus; there is no evidence that TRT can attenuate or
Tinnitus masker wide band white or pink noise, narrow band white noise, a notched soundfield, frequency or amplitude modulated sound, intermittent pulsed sound, or other patterned sound. Temporally patterned sound may be more effective than white noise or background music in masking tinnitus. Studies have found that bandpass maskers are less annoying than pure tone maskers, that the annoyance rating of bandpass maskers is proportional to bandwidth, that intermittent maskers were more annoying than continuous ones, and that control over the center frequency and bandwidth was important in minimizing the annoyance of maskers. In addition to the spectrum of masking sound, the
