Brown noise for studying: does it actually help?

What brown noise is

"Coloured" noises are random sound spread across many pitches. The colour tells you where the energy sits.

White noise has equal energy at every pitch. It sounds like hiss or TV static. Pink and brown noise have more energy in the low pitches, so they sound deeper, more like rain or a waterfall. Brown is the deepest of the three. That's why many people find it the easiest to listen to for hours.

Is brown noise good for studying? What the research says

Here's the surprising part: almost nobody has tested brown noise directly.

The biggest review so far, published in 2024, pulled together 13 studies of noise and attention. It found no studies of brown noise at all. For white and pink noise, it found a small boost on attention tasks for young people with ADHD or strong ADHD symptoms.

For people without those symptoms, noise didn't help on the lab tasks, and made scores slightly worse.

A 2025 study from University College London tested another popular claim: that brown noise is more calming than white or pink. It measured pupil size, a common sign of how alert the body is, and found no difference between the three.

So brown noise isn't a focus pill. But that's not really what it's for.

What it’s really good at: blurring voices

The research on voices is strong. A 2026 review of 30 studies found that background speech slows reading and hurts comprehension, and speech you can understand does the most damage.

That's where brown noise earns its place. A steady, deep sound in your headphones makes the conversation at the next table harder to follow, so your brain stops trying.

So it works best in the places people actually study and work: libraries with whisperers, cafés, shared flats, open-plan offices. The noisier the room, the more it helps. If you'd rather work to music, focus music for work covers which kinds help and which hurt.

Test it on yourself

Keep it low: just loud enough to blur the voices. If the noise is the loudest thing you notice, turn it down. And pair it with a timer, so you have a clear start and a clear moment to rest.

Then don't take anyone's word for it, including ours. For three days, study with brown noise. For three days, without. Keep everything else the same, and each day write down one number: how many 25-minute blocks you finished. If the brown noise days win, you've found your sound. If not, try rain or library sounds next week.

Our free focus timer plays brown noise with a 15 to 45-minute timer, right in your browser. Sound can quiet the room, but not the pull to pick up your phone when the work gets hard. That pull starts inside you, and it's what CatchScroll's two-minute resets are for. The feelings behind it are in why we doomscroll.

So, how noisy is the place you study?
