Brown Noise
Deep, low and grounding
Brown Noise Player
Updated 6 July 2026
Brown noise is a deep, low-frequency sound whose energy falls about 6 dB per octave as pitch rises, giving it a bass-heavy rumble like a steady waterfall or distant thunder. This free player streams seamless, lossless brown noise that loops for as long as you like.
What does brown noise sound like?
Brown noise sounds like a deep, steady roar — a strong waterfall, heavy rain on a roof, or the low rush of a jet engine. Because its energy sits in the low frequencies, it feels warmer and less hissy than white or pink noise, which many people find easier to relax to.
What is brown noise good for?
People use brown noise to fall asleep, to concentrate, and to cover up distracting low sounds like traffic or a humming fridge. Its deep, even tone gives the brain a constant, non-distracting backdrop. Evidence that any noise improves sleep is still limited: a systematic review of 38 studies (Riedy et al.) found only weak support for continuous noise as a sleep aid, so treat it as a relaxation tool rather than a treatment.
Brown vs white vs pink noise
Brown noise is the deepest of the three, with the highs rolled off; white noise is bright and even across every frequency; pink noise sits in between, balanced and soft like steady rain. If white noise feels too harsh or hissy, brown is usually the calmer choice.
Brown vs white vs pink noise
| Noise | What it sounds like | Best for |
|---|---|---|
| Brown noise | Deep, warm rumble with the highs rolled off | Sleep, focus, low-rumble masking |
| White noise | Bright, even hiss across every frequency | Masking sudden sounds; offices; babies |
| Pink noise | Soft and balanced, like steady rain | Relaxing and deeper sleep |
Brown noise questions, answered
How is brown noise different from white noise?
The energy sits in different places. White noise spreads power evenly across every frequency, so it carries plenty of high-end hiss. Brown noise concentrates its energy low down and rolls the highs off steeply, so it sounds deeper, softer and more like distant rumble. People who find white noise hissy often get on better with brown.
Is brown noise better than white noise?
Neither is universally better. Brown noise is deeper and warmer and is often preferred for sleep and focus, while white noise is brighter and better at masking sudden high-pitched sounds. Try both and keep whichever fades into the background fastest for you.
Is it safe to play brown noise all night?
At a low, comfortable volume it is generally considered safe for adults. Keep it quiet — roughly conversational level or below — and lower it further if you use headphones overnight.
Does the brown noise loop without gaps?
Yes. The audio is a lossless, seamless loop, so it plays continuously with no click or pause at the loop point for as long as you leave it running.
