Pink vs brown

Pink noise softens the highs so it sounds like steady rain, balanced across octaves the way ears hear. Brown noise rolls off even harder into a deep rumble like distant thunder or a waterfall. Both feel less harsh than white noise at the same masking power.

Real synthesis

Pink noise uses the Paul Kellet filter cascade, brown noise integrates random steps with a leaky integrator. Both are computed sample by sample on your device, not downloaded audio files, so playback is endless and gapless.

Pink Brown Noise Gen FAQs

Which is better for sleep, pink or brown?
Try both. Pink suits people who like rain-like hiss; brown suits those who prefer deep rumble. Brown masks low sounds like snoring better.
Is brown noise actually brown?
The name comes from Brownian motion, the random-walk math behind it, not the color.
Can this help me focus at work?
Steady noise masks office chatter and keyboard clicks, which many people find aids concentration. Brown noise is the gentler choice for long sessions.
Why does it sound different from white noise?
White noise is equally loud at every frequency, which ears hear as hissy. Pink and brown tilt energy toward low frequencies, sounding warmer.
Does it work offline?
Yes. The noise buffers are synthesized in your browser after the page loads.
