Pink Noise for Sleep
Pink noise sounds like steady rainfall: softer than white noise, with the low frequencies a little louder than the high ones. Many listeners pick it when white noise feels too harsh and brown noise feels too deep.

What you'll hear
An even, rainfall-like wash that stays consistent in character without ever repeating the same audio. It masks sudden household sounds without adding a hiss that draws attention to itself.
Pink noise vs white noise vs brown noise
White noise: bright, even hiss, all frequencies equal. Pink noise: the same idea, tilted toward the low end, so it sounds softer and more like rain. Brown noise: tilted further still, a deep rumble. Try all three free — the right one is usually the one you stop noticing fastest. The full noise colors guide breaks each one down.

FAQ
Does pink noise loop?
No. It is generated live in your browser using the Web Audio API, so there is no file and no loop point — the sound doesn't restart or repeat, whether you listen for 20 minutes or all night.
Can I play it all night?
Yes. There is no track length to run out, so the sound keeps generating for as long as you leave it playing. The sleep timer is there if you want it to stop after a set time.
Is pink noise free?
Yes — pink noise is free to try, no account needed. You get one free world to keep, plus a 60-second taste of the others. Pro ($9/month or $79/year, with a 7-day free trial on the monthly plan) unlocks the full library and full sleep modes.
What is the difference between white noise, brown noise, and pink noise?
White noise contains all audible frequencies at equal intensity — a bright, steady hiss. Pink noise tilts toward the lower frequencies, sounding softer, like steady rainfall. Brown noise tilts further still, producing a deep, warm rumble. All three mask sudden background sounds; which one suits you is usually the one you stop noticing fastest, and all three are free to compare.
