White, pink & brown noise — live
hear each one, live, while you read
White, pink and brown noise are the same idea — steady broadband sound — with the energy tilted differently across frequencies. White is bright and even; pink leans low and sounds like steady rain; brown is a deep rumble. Below, every definition comes with a button that plays the real thing, generated live.
The three colors, plainly
White noise
Equal energy at every audible frequency. To the ear: bright static — a fan, an untuned radio. The strongest masker of sharp, high sounds, but some find it hissy over long sessions.

Pink noise
Energy falls off as frequency rises, matching how our hearing works — so it sounds even and calm. Rain, rustling leaves and surf are all naturally pink-ish.
tap to flipUse it for: sleep and long focus sessions — softer than white, still masks well. On this site: the Pink noise slider, or simply the Rain itself, which carries the same shape with living detail.
Brown noise
Falls off twice as fast as pink — nearly all bass. A deep, oceanic rumble named for Brownian motion, not the color. Popular for its warm, enveloping weight.
tap to flipUse it for: a heavy, cocooning wash, or under other sounds as a floor. On this site: the Brown noise slider — try Deeper or Abyss, or blend a little under Rain and Thunder.
Noise colors vs real rain
Plain generated noise is perfectly steady — useful, but featureless. Real rain has the pink-noise shape plus living detail: individual drops, gusts, distance. On rainrainsound you don’t have to choose: blend a noise floor under the live rain and get the masking of one with the life of the other. Nothing loops, because nothing is a recording.
Questions
- What is the difference between white, pink and brown noise?
- White noise spreads energy evenly across all audible frequencies and sounds like bright static. Pink noise shifts energy toward lower frequencies, so it sounds softer, like steady rain. Brown noise goes further still — a deep rumble like distant surf, with very little treble.
- Which noise color is best for sleep?
- Many people find pink or brown noise gentler than white for all-night listening because there is less high-frequency hiss. The honest answer is that the best one is whichever you stop noticing — all three mask sudden sounds, which is the main benefit.
- Is rain pink noise?
- Close to it. Steady rain naturally carries more energy in the lower frequencies, which is the defining shape of pink noise — with natural variation on top that plain generated noise doesn't have.
- Can I listen to these for free?
- Yes — rainrainsound generates white, pink and brown noise live in your browser, free, with no account, and you can blend them with rain, ocean and thirteen other sounds.
