How Find My Quiet Sound works

Sound generation

White noise is random samples; pink and brown noise are white noise passed through filters so that energy falls with frequency. Loops are generated with a pre-roll cross-fade so the last sample flows into the first — no click, no gap. Nature sounds are layers of filtered noise with slow modulation and small random events (rain droplets, fire crackles, bird calls, crickets), so they never repeat exactly.

Mixing

Up to five sounds run at once, each with a gain, a low-pass filter and a stereo panner, into a master chain with a gentle limiter. Per-sound loudness trims keep the sliders feeling balanced. Everything ramps — nothing starts abruptly.

Frequency tools

The frequency generator uses an oscillator (or a filtered noise band for hiss-like tinnitus) with 1 Hz resolution from 20 Hz to 16 kHz and a lower level cap than other sounds. Find My Tinnitus Sound is a guided version with an octave check.

Sound Response

Discover What Changes Your Tinnitus plays one-minute test sounds built from seeded noise: a third-octave band-pass around your matched pitch (or broadband noise, 100 Hz to 12 kHz), optionally amplitude-modulated, faded in and out. Every test sound is matched to the others by measured energy at the level you chose, that level is capped, and nothing in the experiment raises it. Five seconds of silence follow each sound before the question, at least 45 seconds of rest separate tests, and a change is timed silently until you say your tinnitus is back to usual. The protocol and the adaptive rules are versioned (RI-WEB-V1.0, RI-ADAPT-V1.1) and shown in the experiment details. How Sound Response works.

Visuals

All visuals are procedural Canvas drawings with a global movement level (Still / Low / Medium / High), a Reduce Motion switch that starts from your device setting (once you change it in the app, your choice is kept), and nothing that flashes.

Accessibility

A skip-to-content link, visible focus rings and labelled controls throughout. On a keyboard, Space plays or pauses, Backspace steps back, and Escape closes the sleep screen and Immerse. Frequency Painting has a slider alternative to drawing, and the Sound Response 0–10 scale can be set with the arrow keys. Every visual can be stilled, and Reduce Motion starts from your device setting.

Safety rules

• Master volume starts at 35% and is never restored above 60%.
• Every sound fades in (about 1.2 s) and out; journeys cross-fade over a minute or more.
• A limiter prevents spikes when layering.
• A warning appears above 75% master.
• No feature raises the volume on its own.

Privacy

No account is required. Your settings, results and creations — including saved mixes, experiment feedback, your Find My Tinnitus Sound result and your Sound Response sessions and profile — stay in local storage on your device. Website visitors can choose to allow limited Google Analytics, which counts visits and pages, four anonymous product interactions (a sound started, 30 seconds of listening, Help Me Find My Sound started or completed) and, for Sound Response, which steps of the experiment were reached (opened, safety accepted, session started or completed, profile viewed) — never which sound, ratings, responses, results or anything you enter. The current iPhone app does not use Google Analytics. See Privacy.
