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 retraining therapy large proportion of dropouts; reported 'success' ratios may not take these subjects into account. There are few available studies, but most show that tinnitus naturally declines over time (years) in a large proportion of subjects surveyed, without any treatment. The annoyance of tinnitus also tends to decline over time. In at least some, tinnitus spontaneously disappears. A Cochrane review found only one sufficiently rigorous study of TRT and noted that while the study suggested benefit in the treatment of tinnitus, the study quality was not good enough to draw firm conclusions. A separate Cochrane review of sound therapy (though they
