Frequently asked questions
What is brown noise?
Brown noise (also called red noise) has much more energy in the low frequencies and rolls off the highs, giving it a deep, soft rumble like a steady waterfall or distant surf. Many people find it warmer and less harsh than white noise.
Does brown noise help with ADHD and focus?
Many people with ADHD report that steady brown noise helps them tune out distractions and stay on task, and there is early research suggesting background noise can aid focus for some. It isn't a medical treatment, but it's free to try — start it, set a comfortable volume, and see whether it helps you.
What's the difference between white, pink, and brown noise?
They differ in how energy is spread across frequencies. White noise is flat and bright, pink noise is balanced and natural, and brown noise is deep and bass-heavy. White can sound hissy, pink sounds like soft rain, and brown sounds like a low rumble. Try each and use whichever you find most comfortable.
