Free White Noise Generator
White, pink and brown noise for focus and sleep.
What is the White Noise Generator?
A steady wash of sound can do what silence can't: mask a barking dog, a noisy office or a restless mind so you can focus or fall asleep. This white noise generator plays smooth, even noise on demand — no track that loops audibly, no app, no account. Pick white, pink or brown and press play.
The sound is generated live in your browser, so it never buffers and uses no data once the page has loaded.

What does this tool do?
It synthesises continuous noise in three 'colours'. White noise has equal energy at every frequency and sounds bright and hissy; pink noise is softer and balanced, like steady rain; brown noise is a deep low rumble, like distant surf. You choose one, set the volume, and it loops seamlessly for as long as you like.
There's no file involved — the noise is computed on the fly, so there's no repeating loop to notice.

Tips
- Try pink or brown noise for sleep and focus — they're gentler than bright white noise.
- Start at a low volume; steady noise works by masking, not by being loud.
- For sleep, set your device to stay awake and keep the tab open so it plays through the night.
- If white noise feels harsh, switch to brown for a deeper, calmer rumble.
- Use it to cover intermittent sounds — a lower steady wash hides sudden noises better than turning it up loud.
Common mistakes to avoid
Playing it too loud
Fix: Masking works at modest volume; loud noise adds fatigue and can affect hearing over time.
Assuming a colour fits everyone
Fix: Try all three — many people find pink or brown easier than white for sleep.
Letting the tab sleep
Fix: Keep the tab open and the screen awake so playback doesn't pause.
Expecting a download
Fix: It's generated live in your browser; there's no file to save.
