The Science of Brown Noise
Understanding why brown noise is uniquely effective for relaxation and focus.
What Makes Brown Noise Special?
Brown noise, also called Brownian or red noise, has more energy at lower frequencies than white or pink noise. This creates a deeper, more powerful sound similar to:
- Strong wind or heavy rain
- A powerful waterfall
- Distant thunder rolling
- The low hum of a plane cabin
Research suggests that low-frequency sounds can help synchronize brain waves, promoting relaxation and deeper sleep states.

Frequently Asked Questions
Is brown noise safe to sleep with all night?
Yes, brown noise is completely safe for all-night use. Keep the volume at a moderate level (around 60-70 decibels, similar to normal conversation) to protect your hearing. Our app includes a sleep timer if you prefer automatic shutoff.
Why is it called "brown" noise?
Brown noise is named after Robert Brown, the scientist who discovered Brownian motion. The sound's random, fluctuating pattern mimics the movement of particles in fluid. It's not related to the color brown.
Can brown noise help with ADHD?
Many people with ADHD report that brown noise helps them focus by reducing distracting stimuli. While research is ongoing, the steady, deep sound can create an ideal environment for concentration and task completion.
Is brown noise better than white noise for babies?
Brown noise can be gentler for babies due to its lower frequencies, which are less harsh than white noise's higher frequencies. However, always keep the volume low and position the sound source away from the baby's crib.
