How to play brown noise
- Press Play. Brown noise fades in over a second.
- Set the Volume just high enough to cover the sounds around you.
- To sleep with it, pick a time under Stop after. It fades out gently when the time is up. Space plays and stops it.
What brown noise sounds like
Brown noise is a low, even rumble with no rhythm or tune. Compared with white noise, which spreads its energy evenly and sounds like a hiss, brown noise puts most of its energy in the bass. Think of standing near a large waterfall, rain on a roof heard from inside, or the steady roar inside a plane.
This page uses your browser to make the noise as it plays. Each moment is new random sound, so you never hear the loop point that recordings have, and each ear gets its own stream, which sounds wider on headphones.
Brown, pink and white
| Noise | Energy per octave | Sounds like |
|---|---|---|
| White | Rises 3 dB each octave | Bright hiss, radio static |
| Pink | Same in every octave | Steady rain |
| Brown | Falls 3 dB each octave | Deep rumble, distant surf |
If brown feels too muffled, try pink noise. The noise generator has white, pink, brown and green in one place.
Tips
- Use the sleep timer. 30 or 60 minutes is enough to fall asleep without hours of sound afterwards.
- Move the speaker, not the volume. Brown noise covers low sounds like traffic and voices through a wall well. If a sound still gets through, put the speaker between you and the noise rather than turning it up.
- Keep the tab open. Closing the tab stops the sound. On phones, a locked screen can pause it in some browsers.
