Tinnitus is the perception of sound in the head or the ears.Typically, an individual perceives the sound in the absence of outside sounds, and the perception is unrelated to any external source. In other words, tinnitus is the sound that only the subjected patient tends to hear.A common cause of tinnitus is inner ear cell damage.Thetinnitus retraining therapy (TRT) is a useful approach to the management and treatment of tinnitus.
In practical terms, TRT is a method aimed primarily at habituating tinnitus-evoked reactions of the brain and body, and secondarily, at habituation of tinnitus perception. Consequently, successful TRT patients are not bothered by their tinnitus, even though they are aware of it. Additionally, the amount of time the successful TRT patient perceives tinnitus is decreased.
