White Noise for Sleep
A steady sound with a sleep timer, so it fades out and stops by itself.
Quick answer: For sleep, choose a low volume and set the sleep timer to 30 or 60 minutes. The sound fades out at the end and stops by itself.
Start with a low volume. Your phone may pause the sound when the screen locks.
How to use it
- Choose white, pink or brown noise.
- Turn the volume to a comfortable, low level. Set a sleep timer if you want it to stop by itself.
- Press Start. The sound plays until you press Stop or the timer ends.
White, pink and brown noise
| Type | What it sounds like | Often used for |
|---|---|---|
| White noise | Even hiss across all pitches, like a radio between stations | Masking background sound |
| Pink noise | Softer, with more low pitches, like steady rain | Relaxing and sleep |
| Brown noise | Deep and rumbling, like a waterfall or a strong wind | Focus and blocking out speech |
Noise is a steady, constant sound that covers other noises. The three types differ in how the sound is spread across low and high pitches. People use steady sound to cover traffic, neighbours or office chatter. Research on whether it improves sleep or focus is mixed, so treat it as something to try and not as a treatment. Keep the volume low and do not play loud noise close to the ears for long periods.
What people use it for
