Frequently asked questions
Does white noise help you sleep?
For many people, yes. White noise is a steady, full-spectrum sound that masks sudden changes in your environment, so you are less likely to be woken by a passing car, a creaking house or a snoring partner.
Is this white noise free to play?
Yes, it plays free in your browser with no sign-up. The Noizio app adds offline playback, a sleep timer and the ability to blend white noise with other sounds.
What is the difference between white noise and brown noise?
White noise spreads energy evenly across all frequencies, so it sounds bright and hissy. Brown noise emphasizes the lower frequencies, so it is deeper and softer — many people find brown noise calmer.
