White Noise With a Sleep Timer

Updated 27 June 2026

A sleep-timer white noise player lets the sound play while you fall asleep, then fade out and stop on its own after a set time. This free player offers 15, 30, 45, 60 and 90-minute timers (or a custom length) across white, brown, pink and other sounds — with no app to install.

Why use a sleep timer for white noise?

A sleep timer lets noise mask distractions while you drift off, then stops it so it does not run needlessly all night. Sleep experts often suggest using noise for short periods at bedtime and setting a timer, giving your ears a quiet stretch once you are asleep.

How the gentle fade-out works

Instead of cutting off abruptly, the player lowers the volume smoothly over the final stretch of the timer before stopping. That soft fade avoids the sudden silence that can stir you awake, so the transition into uninterrupted sleep is seamless.

How to set a white noise sleep timer

Open the player and press play, then choose your sound.
Under "Plays for", tap a timer length such as 30 or 60 minutes (or set a custom time).
Set the volume to a low, comfortable level and lock your phone.
The sound plays in the background and fades out and stops when the timer ends.

Frequently asked questions

Does the white noise stop on its own?

Yes. Once you set a sleep timer, the sound fades out gently and stops automatically after the time you chose, so it does not play all the way until morning.

Can I set a custom timer length?

Yes — alongside the 15 to 90-minute presets you can enter any custom number of minutes, up to several hours.

Does the timer work with the screen off?

Yes. The sound keeps playing and the timer keeps counting down in the background, and it will fade out and stop on schedule even with your phone locked.
