Short version: a free sound-therapy tool for chronic tinnitus. It plays gentle harmonic sounds whose fine structure around your tinnitus frequency is modulated to be maximally unpredictable — aiming to retrain the over-precise brain processing thought to keep tinnitus going. It implements the cross-frequency de-correlating stimulus modulation tested in Yukhnovich et al., Hearing Research 2025 (Newcastle University, open access).
How to use: ① let the guided matcher find your tinnitus pitch (~5 min) → ② pick a hearing profile → ③ listen ~60 min daily for 6 weeks and log your tinnitus loudness.
Evidence status (honest): in one blinded randomized crossover trial (77 completers), this stimulus reduced tinnitus loudness significantly versus placebo (~10% on average, more for some people), and the effect persisted for at least 3 weeks after stopping. It has not been independently replicated yet, and it is not a medical device. If your tinnitus is one-sided, pulsating, sudden, or came with hearing loss, please see a clinician first.
Research says matching works best in a quiet room with headphones, with the probe about as loud as your tinnitus. Use noise-like probes for hiss/static, tones for ringing/whistling.
Already know your tinnitus frequency?
Listen to the probe, then say where your tinnitus sits relative to it (pitch, not loudness). The steps shrink automatically — this "bracketing" is more reliable than jumping straight to a slider.
Octave errors are the classic matching mistake — your tinnitus can masquerade as a pitch one octave off. Play all options, then select the closest to your tinnitus.
Now fine-tune. The probe pulses — a ~1 s burst, then a gap, so you can hear your tinnitus in the silences. Compare in the gaps and drag until the bursts sit at your tinnitus pitch. Tiny mismatch is fine: therapy targets a whole octave band.
Optional sanity check — residual inhibition. After listening to noise centred on the right frequency, tinnitus often goes quieter for a few seconds to minutes. No effect doesn't prove the match wrong, but an effect is a good sign.
Listen to your tinnitus now. Compared to before the test:
Your tinnitus frequency match:
Reliability improves if you re-run this on 2–3 different days and use the average — tinnitus pitch genuinely fluctuates. All matches are saved and included in the JSON export.
This compensates for faded high-pitch hearing so the therapy band stays audible to you — it changes the sound, not the therapy. Every preview is the identical sound; only the treble balance differs. Use headphones, and pick the version that sounds most even across pitch — not the loudest or brightest.
Approximation of the study's 4 profiles — a boost ramping in above ~2 kHz (Mild is deliberately subtle, up to +5 dB). No audible difference between options → pick Flat. A real audiogram beats this guess; laptop speakers often can't reproduce the boosted range at all.
Aim for ~60 min daily for 6 weeks (headphones or speakers — the study allowed both). Effects built up over weeks and persisted ~3 weeks after stopping. Keep the daily log below so you can actually tell.
