About White noise generator

How to use White noise generator
- Pick a sound such as white, pink or brown noise, rain, ocean or fan.

Frequently asked questions
Which noise is best for sleeping?
It is personal. Many people prefer pink or brown noise or steady rain because they sound less harsh than white noise. Try each at a low volume and keep it below loud levels all night.
What volume should I use?
Keep it low, just enough to cover distracting sounds. Loud noise for long periods is not good for your ears, so avoid playing it at high volume through headphones.
