Free brown noise generator for focus, study and sleep
Generate deep, rumbly brown noise online without a recording that repeats. If you want study noise or focus noise without music, this gives you a steady sound to cover everyday distractions. You can layer pink or white noise on top in the player to hear how they change the sound.
How to use it
Play brown noise at a comfortable volume while you work, study, read or settle down for sleep. It works on speakers or headphones. Add a pink or white noise layer if you want a brighter sound.
Who it helps
People who prefer a constant background to silence, including some listeners with ADHD. Noise may mask distractions, but no single color works best for everyone.
Common questions
Is brown noise good for ADHD?
Some research suggests background noise can help people with ADHD focus. A 2024 review found a small benefit from white and pink noise on tasks. Brown noise is less studied, but many people with ADHD say it helps them.
Brown noise vs white noise: what is the difference?
White noise sounds brighter and hissier; brown noise puts more energy in the low end and sounds deeper. Pink noise sits between them. This mix starts with brown noise; you can add pink or white noise layers to see whether a brighter blend suits you.
What noise is best for studying?
There is no universal winner. Some people like brighter white noise, while others find brown or pink noise gentler. Try the brown mix at a comfortable volume, then add a pink or white layer if you want more brightness.
Can I add white or pink noise?
Yes. Start the brown noise mix, then use the noise-layer controls to add white or pink noise and adjust the added layer’s volume.
Can I listen to brown noise all day?
Yes, at a comfortable volume. Keep it well below the level where you'd need to raise your voice to talk over it.
Is it free?
Yes. It's free forever, with no subscription and no account.
