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 the sound is tuned to the pitch, loudness and other qualities of the tinnitus. However, frequencies widely divergent from the tinnitus frequency may also mask the tinnitus, if they are of sufficient loudness. The minimum energy (or loudness) mask is usually one closely matched to the central frequency and bandwidth of the tinnitus. But it has also been discovered that a tinnitus mask close to the frequency of the tinnitus can be ineffective, while a masker with a different frequency or bandwidth effectively masks the tinnitus. This indicates different origins of tinnitus. Tinnitus maskers may use music or natural sounds,
