Noise for sleep
Steady noise helps some people sleep for one simple reason: it narrows the gap between the quiet of the room and the sounds that break into it. A door closing or a truck passing is less startling when the background is already humming. That is the whole mechanism — masking, not medicine — and this page covers the practical habits that make it work: low volume, the right color, and a timer that fades out once you are under.
A typical night mix: mostly brown, a little pink to cover voices and clatter. Set a timer below before you press play.
No timer set — playback continues until you pause it. With a timer, the sound fades out gradually at the end instead of cutting off.
Not a treatment: noise does not cure insomnia or any sleep disorder, and this page is not medical advice. If you regularly cannot sleep, wake unrefreshed, or snore heavily, see a doctor. And keep night-time volume modest — hearing damage from sound that is too loud for too long is a real trade, whatever the sound is.
Volume: as low as still works
The most common mistake is volume. Masking does not need to be loud; it needs to be between you and the disturbance. Start lower than feels useful, then raise it one notch at a time until the sounds that wake you — hallway steps, plumbing, early traffic — stop standing out. If you can clearly "hear the noise" as a presence after a few minutes, it is probably a notch too high. Place the speaker across the room rather than at the bedside, especially for children, and never put a noise source inside or right beside a crib.
Color: brown first, pink for voices
Most night-time listeners land on brown (deep, little high-frequency energy to pull your attention) or pink (balanced, better against voices). The mix above — brown at 80%, pink at 20% — is a sensible starting point if your night includes both traffic rumble and human sounds. The comparison page explains the trade-offs, and your ears over two or three nights are a better guide than any chart.
The timer matters more than the color
Playing noise all night is an option, but many people only need cover for the falling-asleep window and the noisy early hours. A timer also means the room is genuinely quiet by morning. On this player the end of a timer is a fade, not a cut: the gain falls in a straight line to zero over the last 10% of the timer (up to 60 seconds). A sudden stop can wake a light sleeper as surely as a sudden sound — if that is you, the fade is the feature.
A practical pattern: set 45–90 minutes if you fall asleep reasonably fast and your street quiets down; set it longer if the disturbances run all night (shift-worker neighbours, dawn traffic) and accept the all-night trade-off at a lower volume.
Questions
- Should the noise play all night?
- Only if the sounds that wake you run all night. Otherwise a timer saves your ears a full night of unnecessary exposure and leaves the room quiet for the deepest part of the night. Try the timer first.
- Is it safe to sleep with noise every night?
- At modest volumes, steady noise is widely used and generally considered low-risk; at high volumes, any sound can damage hearing over time. "As low as still works" is the rule. We are a tool site, not clinicians — persistent sleep trouble deserves a doctor, not more volume.
- Which timer length should I pick?
- Long enough to cover falling asleep plus the noisy part of your night — 45 to 90 minutes covers most people. The fade at the end means a slightly-too-long timer costs you nothing.
- Headphones or a speaker?
- A speaker, for almost everyone: headphones are uncomfortable to sleep in, can press on the ear, and deliver sound at very close range. If you share a bed and need separate sound, keep headphone volume especially low.
