White noise helps you sleep by masking the sudden sounds that wake you up: traffic, a slamming door, a snoring partner. A steady background hum raises the “noise floor” so small disturbances blend in instead of jolting you awake. Many people also find pink or brown noise — deeper and softer than white — more comfortable for all-night use.
This generator creates every sound live with the Web Audio API inside your browser. Nothing is streamed and nothing is uploaded, so it keeps playing with zero data usage and works even after the page has loaded. Mix layers, set a sleep timer, and let it fade out after you drift off.
Fall asleep in 3 steps
- Open the faymox White Noise Generator.
- Pick a base noise — white, pink, or brown — then layer rain, fireplace, or wind with the mix sliders until it sounds right.
- Set the sleep timer so the sound fades out after you fall asleep instead of playing all night.
FAQ
Which noise color is best for sleep?
White noise is the brightest and masks best; pink noise is softer and many sleepers prefer it; brown noise is the deepest, like a low rumble. Try each for a few nights — there is no universal winner.
Does it use mobile data while playing?
No. The sound is synthesized live in your browser, so after the page loads it uses no data at all.
Can I mix multiple sounds?
Yes — combine the base noise with rain, fireplace crackle, and wind, each with its own volume slider.
