Brown noise generator
A steady background sound can cover distracting noises. Choose a colour, press Play and set the volume as low as still covers what bothers you. The sound is made in your browser: nothing is downloaded or sent.
What research says
Studies on background noise and attention in ADHD have mostly tested white or pink noise, with small and uneven effects; brown noise itself has hardly been studied. It is not a treatment: see it as a comfort tool, and stop if it bothers you. Details and sources are in our article.
Frequently asked questions
Brown, pink or white noise: which is best for focus?
There is no single answer: it depends on the person and on what you need to cover. Many people find brown noise gentler; white noise covers high-pitched sounds better. Try each one for a few minutes at a low volume.
Can I fall asleep with it?
Yes: use the automatic stop so the sound fades out after you fall asleep, and keep the volume low. On a phone, the sound may stop when the screen locks, depending on the browser.
Is brown noise a treatment for ADHD?
No. Some people with ADHD find that background noise helps them focus, but studies are few, mostly on white or pink noise, and results vary. It does not replace an assessment or a treatment by a professional.
Why is there no sound on my iPhone?
On iPhone, sound generated by web pages can be muted when the silent switch is on. Turn it off and press Play again.
