About White Noise Sounds
Key takeaways
- White Noise Sounds has six background sounds – white, pink and brown noise, fan, gentle rain and ocean waves – that you can mix three at a time.
- Every sound is generated in your browser. There are no recordings and nothing to download.
- Keep the volume low. The sounds are for rest and focus, not a medical treatment.

How are the sounds made?
All six sounds are synthesized live with the Web Audio API in your browser: the noise colours from generated random signals, and the fan, rain and waves from shaped noise. Nothing is streamed while you listen, so after the first visit the player also works offline. The site never uses the microphone.
