Tinnitus Retraining Therapy (TRT): What Does the Evidence Show?
Behavioral Treatment
Current evidence
The counseling helps — but the trial designed to prove TRT found its sound generators added nothing.
Evidence strength: Limited (2/5) · Tier 4 — symptom management/coping · Evidence independence: Primarily independent.
A structured program combining directive counseling with low-level sound generators, aiming for habituation over 12–24 months.
Did tinnitus loudness improve?
None shown. No loudness effect shown.
Did tinnitus distress improve?
Moderate. All TRTT arms improved substantially (~77.5% achieved meaningful TQ reduction) — but TRT showed no advantage over standard care.
Loudness means the tinnitus percept itself became quieter (psychoacoustic matching or loudness ratings). Distress means questionnaire scores such as THI/TFI, sleep, anxiety or quality of life improved — the sound may be unchanged. A THI/TFI improvement is never evidence the tinnitus got quieter.
How strong is the evidence?
Its own definitive trial found no advantage over standard care: 2/5, Tier 4.
Has the result been independently replicated?
Conflicting results. Earlier positive reports vs the large NIH TRTT (2019), where TRT did not beat standard care.
What are the limitations?
- TRTT: no meaningful advantage over standard care
- Long, expensive protocol
- CBT beat TRT directly in one trial
What should patients know about safety?
Safety evidence: Strong. Safe.
Is it available?
Regulatory status: Clinical protocol (no device authorization needed).
Availability: TRT-trained audiologists · Europe: Available · Cost (approx.): $2,000–5,000 for a full program incl. devices
What the studies found
TRTT: Tinnitus Retraining Therapy vs standard of care
Scherer RW, Formby C, et al. · JAMA Otolaryngology–Head & Neck Surgery · 2019 · N=151 · Multicenter placebo-controlled RCT (6 US military hospitals)
TRT was not superior to standard of care — all three arms improved substantially (within-group TQ effect sizes −1.32, −1.16, −1.01) with few between-group differences. 77.5% (86/111 with data) achieved ≥7-point TQ reduction at 18 months.
Follow-up analyses attribute most benefit to the counseling component, not the sound generators.
Cognitive behavioural therapy for tinnitus (Cochrane Review)
Fuller T, Cima R, Langguth B, Mazurek B, Vlaeyen JWS, Hoare DJ · Cochrane Database of Systematic Reviews · 2020 · N=2,733 (28 studies) · Systematic review of RCTs
CBT vs no treatment: SMD −0.56 (95% CI −0.83 to −0.30; ≈10.9 THI points lower; 10 studies, 537 participants; low certainty). CBT vs audiological care: THI −5.65 points (95% CI −9.79 to −1.50; 3 studies, 444 participants; moderate certainty). CBT vs TRT: −15.79 points (95% CI −27.91 to −3.67; ONE study of 42 participants; low certainty). Essentially no reported harms.
Also reduced depression (SMD −0.34) and anxiety (SMD −0.45, very low certainty). Only weak, if any, effects on perceived loudness.
