Tinnitus Retraining Therapy (TRT) is one of the most widely used approaches to tinnitus management. It combines sound enrichment — usually low-level broadband noise — with directive counselling, aiming to reduce the contrast between the tinnitus signal and background sound over time.
TRT can help. Particularly in the early stages, reducing the acoustic contrast makes the tinnitus less noticeable. Many people find sound enrichment useful at night, when silence makes the sound feel louder.
But TRT has a ceiling — and for many people, it leaves something unaddressed.
What TRT doesn't reach
TRT works on the acoustic experience. It doesn't work directly on the nervous system's psychological response to the sound.
When the masking device comes out, the unprocessed threat response is still there. The monitoring. The checking. The dread before a quiet room. TRT doesn't touch those — because they live in the nervous system's learned behaviour, not in the acoustic signal.
Dependency on sound therapy — while understandable — is also the opposite of what habituation requires. Habituation is the brain learning that tinnitus is safe, even in silence. Sound therapy that prevents silence prevents that learning from happening.
What ACT does differently
ACT — Acceptance and Commitment Therapy — works on the nervous system's relationship to the sound, not the sound itself.
The goal isn't to make tinnitus quieter. It's to make the threat response smaller — until the brain stops treating tinnitus as a priority signal and begins to filter it the way it filters other background sounds.
For people who've tried TRT and found partial relief, ACT often addresses what TRT couldn't quite reach. The two aren't incompatible — sound enrichment can be a useful tool during an ACT-based programme — but they operate at different levels.
