The hum you can't put a name to
Ask someone what's wrong with their office and they'll shrug. Nothing in it is loud. There's a vent that drones, a fridge in the kitchen that cycles on and off, an elevator motor behind the wall, a road outside the window. All of it is a deep sound, and brown noise is a deep sound too, so it covers that kind of hum better than anything brighter would.
It opens a little under half volume, which covers the hum without the sound becoming something you notice on its own. You'll know it's working when you stop hearing the room, and if you catch yourself listening to the noise, it's up too high.
Open office, and the person on a call
Brown noise has been the internet's default focus sound for a couple of years, and a lot of people are running it in offices where the real problem is people talking. Against speech it does very little. A rumble sits underneath a voice and leaves the words sitting clearly on top of it.
The test takes ten seconds. Press play, then see whether you can still follow the conversation across the room. If you can, you want something brighter: white or pink noise is loudest at about the pitch speech sits at, so it blurs the words, and rain does a softer version of the same thing. No sound removes a voice, which is why people sitting near a phone-heavy desk end up pairing noise with over-ear headphones or a move to another seat.
Fifty minutes, then get out of the chair
The timer is the part of this preset worth keeping. Fifty minutes is long enough to get somewhere and short enough that you notice it ending, and a sound that stops is a cheaper cue than a clock you have to keep checking.
When it fades, get up and move for a minute or two. Coming back is the moment to change something: less volume if you caught yourself listening to it, or the wind pulled to zero if a bit of movement was all you could hear. The timer row under the player also has 30 and 60 minutes if your day runs in different pieces, and Off if you want it going until you stop it.
One thing to watch in a shared office: if you're waiting on a call or someone might need you, keep the level low enough that your name still gets through. Noise-canceling headphones with noise playing on top of them is how people miss things.
For your next work block
- Press play. Brown noise starts at 45%, wind at 15%, and the timer is on 50 minutes.
- Listen for whether the hum has flattened, then set the level.
- If you can still follow people talking, switch to the white noise focus preset, which blurs speech better.
- When the timer runs out, get up and move before you start another block.
Frequently asked questions
Is brown noise good for focus?
For a room that hums, it's the best fit here. Air handling, a fridge, an elevator motor and traffic through the floor all sit deep, and brown noise sits down there with them. Against people talking it does almost nothing, so if that's your office, white or pink noise blurs speech far better.
Does brown noise make you more productive?
It can make a distracting room less distracting, and that's as far as the evidence goes. No study shows a steady sound raises your output. What people do notice is that they stop looking up every time the vent kicks in, which is a smaller claim and an easier one to check over a week.
Brown noise or white noise for concentration?
Match it to the disturbance. Brown covers a deep rumble, white covers voices and clatter, and neither covers both. If your office hands you a droning vent and a chatty neighbor, run rain or pink noise over the brown and you'll cover more of what the room gives you. Play the two colors back to back for thirty seconds and keep whichever one makes the room go away.
How loud should it be while I work?
Lower than you'd set it to sleep, because awake you notice more. Raise it until the hum stops standing out and then leave it. If you're in headphones all day, keep it gentle in there; a level that feels fine for an hour is a lot of hours by five o'clock.
Will it cover a coworker on a call?
Not on its own. Any sound you play blurs speech and none of them removes it, and brown noise blurs it least of the options here. Add rain or switch to white noise to take the edges off the words, and if calls happen beside you all day, over-ear headphones do more than any setting on this page.
Does brown noise help you focus if you have ADHD?
Many people with ADHD say it does, and it's the sound they name most often for getting started. Treat that as what people report and nothing more; the studies on background noise and attention point both ways, and none of them tested brown noise. Try one work block with it and one without, and keep anything about diagnosis or medication with a doctor.
Headphones or a speaker at my desk?
Either one, as long as it isn't a bare laptop speaker, which can't push out the deep part of brown noise and plays you a thin hiss instead. A small speaker on the desk is easier in a room of your own. In a shared office, over-ear headphones do double duty by blocking part of the room before the sound even starts.
