Brown Noise, Rain or Lo-fi? How to Choose Focus Sounds for Studying
Does background noise help you study? Compare brown, pink and white noise, rain, café sounds and lo-fi, and learn how to pick the right sound for each task.

Key takeaways
- Steady, predictable sounds (rain, brown noise, café hum) mask distracting noises without demanding attention.
- Music with lyrics usually hurts reading, writing and memorising, because it competes for the language parts of your brain.
- Brown noise is deeper and softer than white noise; many people find it more comfortable for long sessions.
- Effects vary a lot between people: test sounds for a week and keep the volume low.
Some people need total silence to study. Others can't concentrate without rain sounds or a lo-fi playlist. And then there's brown noise, which has gone from audio jargon to one of the most searched study aids around. So what actually helps you focus?
Here's what we know about background sound and concentration, a comparison of the most popular focus sounds, and how to find what works for you.
Why background sound can help, or hurt
Your brain is constantly scanning for changes in sound. A door slamming, a conversation nearby, a notification ping: each one grabs a little attention, even if you don't look up. That's useful for survival, terrible for studying.
Steady background sound helps in two ways:
- Masking: it fills the silence, so sudden noises stand out less.
- Signalling: putting on “your” study sound becomes a cue that it's time to focus.
But sound can also hurt. Research on the so-called irrelevant speech effect shows that hearing words, even when you're trying to ignore them, interferes with tasks like reading, writing and memorising. That's why music with lyrics and nearby conversations are so distracting while you study.
The popular focus sounds compared
| Sound | What it's like | Good for | Watch out for |
|---|---|---|---|
| Brown noise | Deep, soft rumble, like a distant waterfall | Long sessions, masking low hums and voices | Can feel muffling at high volume |
| Pink noise | Balanced, like steady rain | General focus, a softer alternative to white noise | Some find it monotonous |
| White noise | Bright hiss, like radio static | Masking sharp, high sounds | Harsh for many people over long periods |
| Rain & thunder | Natural, slightly varied | Calm reading and writing | Loud thunder can startle |
| Forest, river, ocean | Natural, gentle variation | Relaxed focus, reducing stress | Birdsong can catch attention |
| Café | Soft chatter and clinks | People who focus better around others | Clear voices can distract during reading |
| Lo-fi music | Slow, instrumental beats | Repetitive tasks, mood | Musical changes can pull attention |
| Silence | Nothing at all | Hard reading, memorising, exams practice | Every small noise stands out |
Brown noise vs white noise vs pink noise
These “colours” describe how sound energy is spread across frequencies:
- White noise has equal energy at all frequencies. To our ears it sounds bright and hissy.
- Pink noise turns down the high frequencies. It sounds softer, a lot like steady rain.
- Brown noise turns them down even more, leaving a deep rumble. Many people find it the most comfortable for long periods.
Is there science behind it? Some studies have found that background noise helped attention for certain people, for example research by Göran Söderlund and colleagues suggesting that white noise improved performance for some inattentive children while not helping others. The overall evidence is still limited and mixed, so treat focus sounds as a personal tool to test, not a guaranteed boost.
Matching sounds to tasks
- Reading and memorising: silence, brown noise or soft rain. Avoid lyrics.
- Writing: brown or pink noise, or nature sounds.
- Maths and problem-solving: whatever keeps the room steady: brown noise is a common favourite.
- Repetitive tasks (formatting notes, flashcard making): lo-fi or music you like can lift your mood.
- Noisy environments (shared rooms, libraries): a masking sound through headphones, at low volume.
Tips for using focus sounds well
- Keep the volume low. Just loud enough to soften surrounding noise. Protect your hearing, especially with headphones over long days.
- Use the same sound for the same kind of work. Over time it becomes a trigger for focus.
- Try mixing. A natural sound on top of a noise colour often feels richer and masks better than either alone.
- Don't fiddle. Choose your sound before the session. Hunting for the perfect playlist mid-session is a distraction in itself.
- Test for a week. Try two or three options and notice which sessions felt easiest and which got the most done.
A simple experiment
- Days 1–2: study in silence (or as quiet as you can get).
- Days 3–4: brown noise at low volume.
- Days 5–6: rain or forest sounds.
- Day 7: compare. How many sessions did you complete? How often did you get distracted?
Counting distractions makes this comparison much more objective than just going on feel.

Questions people ask
Does brown noise help you focus?
Many people find it helps by masking distracting sounds with a steady, low rumble that's easy to ignore. Scientific evidence specifically for brown noise is limited, and effects differ between people, so try it for a few sessions and see how you feel.
What is the difference between white, pink and brown noise?
White noise has equal energy across all frequencies and sounds like a hiss. Pink noise has less energy in the high frequencies and sounds softer, like steady rain. Brown noise has even more emphasis on low frequencies and sounds like a deep rumble or distant waterfall.
Is it better to study in silence or with music?
For reading and memorising, silence or steady non-verbal sound is usually best. Music with lyrics tends to interfere. For repetitive tasks, some people find upbeat music improves mood and pace. If your surroundings are noisy, a masking sound is often better than trying to tune out voices.
Is lo-fi music good for studying?
Lo-fi is popular because it's instrumental, slow and repetitive, so it's less distracting than music with lyrics. If you find yourself listening to it rather than studying, switch to a plainer sound like rain or brown noise.
