White noise player: sleep sounds for a better night
Generate soothing white noise, deep brown noise, or rain sounds directly in your browser — free, with no download and no ads playing over the sound.
How background noise helps you sleep
A steady, predictable sound masks sudden noises — a door closing, traffic, a partner moving — that would otherwise pull you out of sleep or keep you from settling in the first place. White noise covers a broad range of frequencies evenly, brown noise emphasizes deeper, lower tones many people find more soothing, and rain sounds add a natural, textured layer that many find easier to sleep to than steady noise alone.
Frequently asked questions
What's the difference between white and brown noise?
White noise has equal energy across all frequencies, and can sound harsh or hissy. Brown noise emphasizes lower frequencies for a deeper, softer sound many find more relaxing.
Is it safe to play noise all night?
Yes, at a moderate volume it's generally considered safe. Keep the volume low enough that you could comfortably hold a conversation over it.
Does this work on mobile?
Yes — it runs entirely in your browser using the Web Audio API, so it works on phones, tablets and computers without installing anything.
