The Best Noise for Sleep

The best noise for sleep is the one that masks your distractions and feels soothing to you — and the fastest way to find it is to try them. Press play, switch colors with the selector, and set a sleep timer to test each one tonight.

Below is a quick guide to which color suits which sleeper, with links to a dedicated player and guide for each.

Which noise color is best for sleep?

All the noise colors mask disruptive sounds, but they differ in tone. Here is how the popular sleep colors compare, from deepest to brightest:

  • Brown noise — deep, warm rumble; a favorite for sleep and relaxation.
  • Pink noise — balanced and rain-like; the most research-backed for deep sleep.
  • Green noise — mid-focused, nature-like; soothing and grounding.
  • White noise — bright and even; masks the widest range of sounds.

How to use noise for better sleep

Keep the volume low — just enough to blur the sounds around you. Use the Sleep Timer to fade the noise out after you fall asleep, position the speaker away from your head, and give a new sound a few nights before judging it. If one color feels harsh, move toward a deeper one (brown or pink).

Frequently asked questions

What is the best noise for deep sleep?

Pink noise has the strongest research support for deep, slow-wave sleep, while brown noise is the most popular for its soothing, deep tone. Both are excellent — try them above and keep the one that helps you fall and stay asleep.

Should I play sleep noise all night?

You can, but many people prefer a sleep timer that fades out after they fall asleep, which saves battery and rests the ears. If you wake easily to later noises, all-night playback keeps masking them.

How loud should sleep noise be?

Keep it moderate — around 50 decibels or lower, similar to a quiet shower. Loud enough to mask distractions, no louder, to protect your hearing over long nights.
