If it sounds like a thin hiss
Most of brown noise sits low enough that a phone speaker can't really produce it, so on a phone you get a faint hiss and wonder what the fuss is about. Anything with a proper driver shows you the difference: headphones, or a speaker you'd play music through.
You're probably reading this on a phone, and the cheapest fix is low-profile sleep earbuds you can lie on. A small bluetooth speaker works too, on the floor or across the room rather than beside your pillow. A laptop gets you part of the way.
Wherever the sound comes out, set the level while the road is actually busy, because a level you pick in the quiet before bed will be too low by midnight. If earbuds are staying in until morning, keep it gentle in there.
Resist turning it up
When you can still hear traffic through it, the urge is to push the volume until the traffic disappears. A truck at the lights is louder than your speaker will ever be, so the traffic wins and you sleep in twice as much noise.
Aim for the level where the next truck doesn't jolt you. You'll still hear it if you go looking for it, and what changes is that you stop waking up to check.
Where it helps, and where it doesn't
Brown noise works under the room: rumble from the apartment below, a boiler, the highway. Speech is the hard one, and not only for brown noise, since your ear keeps hunting for words in whatever you play. A neighbor's conversation through the wall gets blurred rather than removed, and white or pink noise blurs it better than brown does. Rain sits in between, softening the mid and high sounds while low rumble passes through it.
People leave it on for more than traffic. Night-shift workers sleep through a bright, busy afternoon with it. Someone with a snoring partner uses it so the gaps between snores stop being the loudest part of the night, and people with tinnitus, or a head that won't stop narrating, often say a low steady sound is easier to lie in than silence.
None of that makes it a treatment, and we won't pretend otherwise. What it changes is what your room sounds like. If your nights are bad and the room is already quiet, sound is the wrong tool.
Tonight
- Press play. It opens at half volume, which is a sensible place to start.
- If all you hear is a faint hiss, you're on a phone speaker. Move to earbuds or a real speaker.
- Set the level while the street is busy, not in the quiet before bed, and check your alarm still cuts through it.
- Leave the sleep timer on All night for eight hours, or tap 30 min or 60 min if you only need help dropping off.
Frequently asked questions
Is brown noise good for sleep?
If what wakes you is a deep rumble, yes: traffic, a boiler, footsteps and bass from the apartment below all get easier to sleep through. Voices are the weak spot. White or pink noise blurs a conversation better than brown does, and no sound you play removes one. Plenty of people also just find a deep steady sound easier to lie in than a silent room.
How loud should brown noise be at night?
Quieter than feels right at first. Loud enough that a passing truck doesn't jolt you and no louder, because trying to drown out the street means sleeping in more noise than you started with. Set it while the street is busy, then leave it alone.
Can I leave brown noise on all night, or is 30 minutes enough?
Both work, and the sleep timer row under the player is where you choose. It arrives on All night, which runs eight hours, long enough for a road that's busy at four as well as at midnight. Tap 30 min or 60 min if the noise is only around while you're falling asleep, or Off to let it play until you stop it. Either way, play your alarm once over the top and make sure you'd wake to it.
Will brown noise cover my partner's snoring?
Partly. It softens the deep part of a snore, which is often the part that carries through a wall, but the sharper edges still come through from the next pillow. Most people who manage it pair earplugs with sound in the room. If the snoring comes with gasps or long pauses in breathing, that's worth a doctor's visit.
Does brown noise help with tinnitus or a racing mind?
Many people use it for both and describe it as a comfort, something easier to lie in than a silent room. Keep it soft and give it a week before you judge it. If your tinnitus is new or getting worse, take it to a doctor or an audiologist.
Which color of noise is best for deep sleep?
Brown suits most bedrooms, because what comes through a floor or a window is mostly a deep rumble, and brown noise is a deep rumble too. White and pink are worth trying when the problem is voices or clatter, and rain does a gentler version of the same job. When a street hands you both, rain over brown noise covers more of what the room throws at you without turning bright.
What should I play it through in bed?
Earbuds are the easy answer, and low-profile ones let you lie on your side. Otherwise a small bluetooth speaker a little away from the bed, which is all a bedside sound machine really is. The one thing to skip is the bare phone speaker, which can't push out the deep rumble you came for.
