Brown Noise for Sleep

Try brown noise for sleep if traffic, building hum or other low sounds wake you, or if white noise feels harsh. Play it from a bedside speaker at a low volume, all night if you wake easily. Skip it if you mostly need to cover voices or sharp, high sounds; white noise covers those better. For the basics, see the brown noise guide.

You can also mix brown noise with other sounds in the free Soundscape Lab, which has a sleep timer.

Why people choose it for sleep

• It covers low sounds: traffic, a neighbor's bass, a heating system and footsteps through a wall sit in the low range where brown noise concentrates its energy.
• It feels warmer: it has less hiss than white noise, so many people find it cozy, like weather, and easier to tolerate for hours.
• It gives a steady background: brief sounds like a car door are less likely to stand out against a constant floor.

Brown, white or pink for sleep

• White noise: better for covering voices, phones and sharp bangs, but harsh over long sessions for some people. See brown noise vs white noise.
• Brown noise: better for low-frequency disruption like traffic, snoring and building noise. If white noise helps but leaves you tense, brown is a likely next step.
• Pink noise: in between, with more research behind it. A 2017 study reported that pink noise played during sleep improved slow-wave activity in older adults. Brown noise has not been studied as directly, so try each for a week. See the pink noise guide.

Who it suits

• Light sleepers: steady masking means small sounds stay below the baseline.
• City dwellers: urban noise is mostly low rumble.
• Shift workers sleeping by day: it can help with daytime traffic.
• A busy mind at bedtime: some people say the steady sound gives their thoughts something to settle against. This is anecdotal and not proven.

All night or on a timer

All night suits people who wake easily or get woken by early morning sounds. Waking to silence when the sound was there as you fell asleep can make returning to sleep harder. A timer suits people who sleep through light noise and only need help falling asleep. Try all night first for a week.

Speaker or earbuds

A small Bluetooth speaker at head height a little way from the bed is usually best. Earbuds all night are uncomfortable, and over-ear headphones fall off. You do not need much bass response. If a partner objects, a pillow speaker or one earbud are compromises. Silence notifications so a buzzing phone does not cancel the effect.

Volume and habit

• Start low and raise it slightly if sounds break through. It should be audible but not demanding.
• Use your speaker's lowest comfortable setting, and move it closer instead of turning it up.
• Becoming used to it is a common worry. You can bring a phone noise app when traveling.

Using it under ASMR

Brown noise works as a quiet floor under tapping or whispering, because it is featureless and does not compete with triggers. Keep it clearly in the background. See the best ASMR for sleep list, sound therapy and ASMR, the ambient sounds overview and rain sounds for sleeping for more natural-feeling options.

What the research says

The 2017 pink noise study above is the only study named on this page, and it does not cover brown noise. The rest is common practice, not tested results. See also whether ASMR is good for you.
