Questions people ask
Does white noise help you sleep?
Many people find it does. Steady sound masks sudden noises like traffic, voices or a snoring partner, which are what usually wake us. Studies on white noise and sleep are mixed, so try a few sounds and see what works for you.
What is the difference between white, pink and brown noise?
White noise has equal energy at all frequencies and sounds like hissing static. Pink noise has less high end and sounds like steady rain. Brown noise is deeper still, like a strong waterfall or distant thunder. Many people find pink or brown noise more relaxing than white.
Will the sound keep playing when my phone is locked?
Usually, yes. The sounds play like music, so on most phones they continue with the screen locked. If your phone stops them, turn on Keep screen on and dim the screen instead.
Does the sleep timer turn the sound off?
Yes. Pick 15 minutes to 8 hours and the sound fades out gently over the last 30 seconds, then stops. Choose Play all night to keep it going.
Can I play my own music with the clock?
Yes. Tap Choose songs and pick one or more songs from your phone or computer. They play in order (or shuffled) right on the page, next to the clock, and the sleep timer works with them too. Your files never leave your device.
Is the music free to use?
Yes. All the built-in music on this page is original and is generated in your browser, so there are no ads, no accounts and no downloads.
Do the sounds use data?
No. Every sound is generated inside your browser, so after the page loads nothing more is downloaded.
How loud should sleep sounds be?
Keep them quiet, around the level of a soft shower or gentle conversation. Experts suggest staying well below 50 decibels for all-night listening, especially for babies.
