Can Tinnitus Treatments Reduce Loudness, Distress, or Both?

The short answer

Most tinnitus treatments with good evidence reduce distress — how much tinnitus bothers you — rather than the loudness of the sound itself. The questionnaires used in most trials (THI, TFI) measure impact on your life, not volume. A treatment can meaningfully improve your life while the sound stays the same — and a questionnaire improvement is never proof the sound got quieter.

Treatments with at least moderate loudness evidence

• Auricle bisensory stimulation (Susan Shore device) — Loudness was a CO-PRIMARY endpoint, measured by psychoacoustic loudness matching (dB SL): within-participant change −7.2 dB per-protocol (p=.03) at week 6, deepening to −14.1 dB by week 12 of the second active phase — the strongest percept-level result of any tinnitus RCT. These are changes during treatment, not active-minus-control differences.
• Cochlear implants (for qualifying hearing loss) — Percept-level ranges (Ramakers 2015, Laryngoscope): tinnitus decreases in 25–72% of implanted patients and is completely suppressed in 8–45% — while 0–25% experience worsening and ~9% develop new-onset tinnitus. The 2024 meta-analysis adds a pooled tinnitus VAS −3.1 (a mixed scale covering annoyance/loudness/awareness, not pure loudness).
• Venous sinus stenting (pulsatile tinnitus) — In correctly selected venous-stenosis patients, pooled analysis of 28 studies (N=616): 91.7% improvement and 88.6% complete resolution of the pulsatile sound. This is elimination of the percept — in a specific, imaging-confirmed subgroup.
• Sigmoid sinus wall reconstruction (pulsatile tinnitus) — Uncontrolled series report elimination of the pulsatile sound in most correctly selected patients (pooled 77.6% complete resolution; 83.8% durable at 5+ years in the longest cohort; ~65% under stricter definitions). Rated moderate, not strong: no controlled data, and outcome definitions vary widely.

Note how short this list is, and how population-specific its entries are — that is the honest state of the science.

Why we never blur the two

Distress improvements are real and valuable — better sleep, less anxiety, a life that feels normal again. But telling someone a treatment "reduces tinnitus" when trials only measured questionnaires misleads them about what to expect. Every treatment page on this site rates loudness evidence and distress evidence separately. The measurement standards behind this — TFI, THI, and the COMiT'ID core outcome consensus — are documented in our methodology.
