THREE SIMPLE STEPS
How to use the white noise generator
Set the mix
Adjust each sound's volume and the main volume. Add up to 8 sounds.
Press Play
Set a sleep timer if you like: it fades out gently over the last minutes and stops.
Calm sound, made fresh every second
Real noise colours
White, pink (−3 dB per octave), brown (−6 dB), blue, violet and grey noise, measured to within 0.2 dB per octave of their definitions.
Never loops
Nothing is a recording played on repeat: each sound is computed live from a random generator, so you won't notice a seam or a pattern, even after hours.
Nature and ambience
Light and heavy rain, rain on a roof, distant thunder, ocean waves, wind, a stream, a fireplace, night crickets, a fan, an airplane cabin and a ticking clock.
Mixer and quick mixes
Combine up to 8 sounds with their own volume, or start from Sleep, Focus, Study, Baby, Tinnitus relief, Sound masking, Storm, Campfire or Beach.
Sleep timer
Choose 15 minutes to 12 hours. The sound fades out slowly over the last part so it doesn't wake you when it stops.
Sleep screen and download
A black sleep screen keeps the room dark. Download a few minutes as a WAV file to play offline.
Tips for better sleep and focus
Lower than you think
Set the volume just loud enough to cover distracting sounds. Quieter is better for long listening.
Brown for sleep, pink for focus
Deep brown noise is soothing for many people at night; pink noise is gentler than white for working.
Mask voices with pink plus a fan
The Sound masking mix covers speech in an open office better than white noise alone.
Phones and the lock screen
Some phones pause web audio when the screen locks. Use the sleep screen, or download a WAV file and play it in your music app.

White noise FAQ
Is this white noise generator free?
Yes. No account, no limits, no adverts in the sound.
What is the difference between white, pink and brown noise?
White noise has equal power at every frequency and sounds like a bright hiss. Pink noise falls by 3 dB per octave and sounds softer, like steady rain. Brown noise falls by 6 dB per octave and sounds like a deep rumble or a distant waterfall.
Does it loop?
No. Every sound is generated live from a random source, so it never repeats. We checked 10-minute renders of every sound and found no repeated stretch.
Will it keep playing when my screen is off?
On computers it keeps playing in a background tab. Some phones pause web audio when the screen locks; keep the page open with the sleep screen, or download a WAV file to play offline.
How does the sleep timer work?
Pick a length from 15 minutes to 12 hours. The sound fades out over the last quarter of the time (between 1 and 10 minutes) and then stops.
Is white noise safe for babies?
Many parents use it, but keep it quiet, keep the speaker away from the cot and use the sleep timer. Ask your doctor if you are unsure.
Can noise help with tinnitus?
Some people find gentle background sound makes tinnitus less noticeable. This is not a treatment; please talk to a doctor or an audiologist about tinnitus.
Is anything uploaded or streamed?
No. The sounds are computed in your browser; nothing is downloaded while you listen and nothing is sent anywhere.
