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 in 90% of persons but in rare cases, an hour or more. The period of complete silence is usually seconds to about a minute. If the trigger sound is repeated at intervals, tinnitus can be suppressed as long as the repetition lasts. The residual inhibition (RI) effect first noted in 1903: the capacity of a sound of the right frequency and intensity to briefly attenuate or suppress tinnitus. To distinguish the tailored sound used for inhibition from the broadband undifferentiated sound employed in tinnitus maskers, it is usually referred to as the 'trigger' or 'quieting' sound. The trigger sound is
