Brown Noise
Deep, warm noise
Brown Noise
Deeper and warmer than white noise — all soft, low rumble.
Why brown noise helps
- Brown noise emphasises the low, deep frequencies, giving a soft rumble many people find gentler and less hissy than white noise.
- It's become especially popular with people who have ADHD, who say it quiets a busy mind for sleep or focus.
- Like any steady noise, it masks background sounds so they don't pull you out of rest.
