The aim of Tinnitus Retraining Therapy (TRT) is to desensitize the perception of tinnitus by listening to an array of sounds, preferably from world of nature or white noise (noises composed of the sum of several tones). Also effective in treating tinnitus in the morning, TRT uses devices that promote relaxation through the emission of sounds chosen by the user, thereby enabling you to mask the perception of tinnitus.
