Brown Noise for Sleep
Ten hours of deep rumble, an adjustable sleep timer, and nothing to install.
Press play and put the phone down. The bar at the bottom sets a timer that fades the sound out on its own, or you can let it run until morning with the screen dark.
Why the low end helps at night
It is the jump from quiet to loud that wakes you, not loudness itself. In a sleep-lab study that replayed recorded ICU noise, arousals rose from about 13 to 48 per hour; layering white noise over the same recording brought them back to about 16 (Stanchina 2005). A steady sound narrows the gap between background and spike, so the door click or passing truck no longer registers as news.
Most of what intrudes on a bedroom at night is low-pitched: traffic, a snoring partner, footsteps overhead. Brown noise concentrates its energy in that same low range, which is why many people find it covers those sounds more comfortably than a bright hiss. Fair warning on the research: brown noise has almost no sleep studies of its own, and the evidence for any continuous noise as a sleep aid is rated "very low" (Riedy 2021). Masking is the one job it verifiably does.
Using the player all night
The loop is gapless, so there is no seam to wake you at hour three. Tap the moon icon for Black Screen mode and the page goes dark while the sound continues, which spares your eyes and your battery. Data use is small enough to stream all night, and the volume slider remembers where you left it.
Volume rule of thumb: quieter than you think. The sound should sit under the room, not on top of it. If you can comfortably talk over it, you are close; if you notice it once you stop moving, take it down a step.
Timer, or all night?
Masking only works while the sound is playing. If your problem is falling asleep, set the timer for 30 to 90 minutes and let it fade once you are under. If you wake when the room changes, or your street gets loud at 5 a.m., leave it running quietly until morning. Both are ordinary ways to use it; pick the one that matches when your nights go wrong.
Common questions
Is it OK to sleep with brown noise all night?
At a low volume, the research gives no reason to avoid it: a review of 34 nighttime noise studies (1,103 participants) reported no adverse effects from short-term use (Capezuti 2022). Keep it quiet enough to talk over. Babies play by stricter rules, covered on our baby page.
Does brown noise cover snoring?
Often, yes. Snoring is low-frequency, and masking works best when the masking sound shares the range of the sound it hides, which is where brown noise lives. It will not silence a loud snorer, but it can blur the starts and stops that do the waking.
Should the sound turn off after I fall asleep?
Either way works for adults. A timer avoids playing sound your sleeping brain no longer needs; running it all night keeps the masking in place for early-morning noise. If you wake when it cuts out, use a longer fade or leave it on.
Is brown noise better than white noise for sleep?
No study has run that comparison overnight. Both mask; brown does it without the hiss, which is the whole reason to prefer it. The sound you will keep on at low volume every night is the one that works.
