White noise: what it’s for and how to use it to sleep

A slamming door, a neighbor coming home late, a snoring partner… It’s not always loud noises that wake us up, but sudden noises that break the silence. That’s where white noise comes in.

What is white noise?

It’s a continuous, steady sound, much like the hum of a fan or the static of a radio. More broadly, the term white noise is also used for other soothing background sounds: rain, waves, a stream, or the forest.

How does it help you sleep?

The principle is simple: a soft, constant background sound reduces the contrast between silence and sudden noises. A slamming door is less noticeable, and your brain is less likely to startle. Many people also find that a steady sound helps them switch off and stop ruminating.

Who is it for?

  • Those who live in an apartment or on a noisy street
  • Those who share a bedroom with a snorer
  • Light sleepers who are woken by the slightest noise
  • Travelers, whether staying in a hotel or with friends
  • Parents, for a baby’s room (placed at a safe distance and at a moderate volume)

How to use it effectively

  1. Place the device at a distance: on the bedside table, one or two meters from your head, not against the pillow.
  2. Set it to a moderate volume: just loud enough to mask background noises, like a shower running in the next room.
  3. Choose your sound: pure white noise to mask as much as possible, or rain or waves if you prefer a more natural sound.
  4. Use a timer if you don’t want it to run all night.
  5. Be consistent: used every night, the sound becomes a sleep cue for your brain.
