Your tinnitus has a pitch.
Find it, then take it out of the noise.
Match the pitch in your head. Then play noise with that exact band cut out.

Find your frequency
Pick the voice closest to yours, press ▶, drag until the tone melts into your tinnitus. Then lock it.
Press ▶ or drag the slider.
How do I know I found it?
- The flutter stops - you are on it.
- A sudden loudness bump - you are close.
- Come from below, then from above. Where both agree wins.
- Tone vanishes up high? That is your hearing limit. Go back down.
Notched noise
Noise with a hole cut at your frequency, to quiet the over-active neurons. Still hear your tinnitus through it? Normal. Keep it low, give it weeks.
± 0.5 octave is what the studies used. Narrower = precise, wider = gentler.
Notch doing nothing? Compare with depth at −6 dB (notch closed).
Binaural beats optional
One tone per ear, under the noise. Maybe relaxing - no real evidence it helps tinnitus.
Only plays while step 2 runs.
Live audio graph
The real audio chain, live. Once locked, the gap in the spectrum is the notch - the whole treatment, drawn.
What the evidence says
Real idea. Modest effect.
- 2010 · PNAS (Okamoto): music with a one-octave notch lowered tinnitus loudness.
- 2025 meta-analysis · Eur Arch Otorhinolaryngol 282:3431: 14 trials, 793 patients, −8.6 THI points vs normal music (95 % CI −17.0 to −0.2). Barely above zero.
- 2021 RCT · J Int Adv Otol, 104 patients: no significant difference.
- Biggest caveat: the trials used notched music, not notched noise like this page.
- Cochrane: low-certainty evidence for all sound therapy. Nobody can promise a cure.
- Binaural beats: nothing credible for tinnitus.
Some find it less intrusive after months. Many feel nothing. It does not replace an ENT.
An experiment, not a medical device. Keep it quiet. Stop if anything gets worse.
