Focus sounds
Sounds that anchor your attention.
Brown noise, pink noise, binaural beats, and pure tones — all generated in real time inside your browser using the Web Audio API. Nothing streamed, nothing tracked. Use stereo headphones for binaural beats.
Why Brown noise?
Brown noise (1/f² spectrum) damps high-frequency distractions. Reported by many ADHD users to help with sustained attention.
Why Pink noise?
Pink noise (1/f spectrum) has equal energy per octave and matches natural sound profiles like rain or wind.
Why White noise?
Equal power across frequencies. Sharper than brown / pink. Some find it grounding, others abrasive.
Why Binaural 14 Hz?
Binaural beats in the beta range (13–30 Hz) are sometimes associated with focused attention in research, though evidence for ADHD is mixed.
Why Binaural 8 Hz?
Alpha range binaural beats (8–12 Hz) are associated with relaxed wakefulness in some studies.
Why 40 Hz tone?
A 40 Hz tone is studied in cognitive research for its possible role in entraining gamma-band neural oscillations. Evidence specifically for ADHD is preliminary.
What these sounds actually do
The honest version: the research on noise and binaural beats for ADHD is mixed. Some controlled studies report meaningful effects on attention and working memory; others find no benefit. What does seem reasonably robust is that continuous low-frequency background sound can mask intrusive distractions and reduce the cognitive cost of constantly re-orienting attention.
For many ADHD users, brown noise in particular is a daily working tool. It does not "cure" anything, and it does not replace medication or behavioural strategies. It is one inexpensive, side-effect-free option to try.
How to use without wrecking your hearing
- Keep the volume low. You should be able to hear someone speak at a normal level.
- Do not use through earbuds at high volume for hours daily. The risk is real.
- Take breaks every 60 to 90 minutes.
- If your ears ring after a session, the volume was too high.
If sounds make your ADHD worse
Some people with ADHD find background sound aversive. Sensory profiles vary. If you try these for a week and they consistently make focus harder, stop. It is not a moral failing or a sign your ADHD is wrong.
Educational only. No medical claim.
These tones do not treat or cure ADHD. They are an accessibility tool that some people find useful. If sound therapy is being marketed to you as ADHD treatment with a price tag, that is a red flag, not a clinical option.
