Some people with Attention Deficit Hyperactivity Disorder (ADHD) are able to concentrate better when they listen to brown noise. For some people with ADHD, brown noise is like a soft blanket for one’s brain. It could work by sound masking: covering other sounds in the background with a continuous hum. Thus, brown noise can also improve sleep, blocking out sudden changes in noise that may wake you up.
There’s a definite possibility that the placebo effect may be responsible for brown noise’s benefits. If you want to believe in brown noise’s healing effects, you’ll likely feel them.Brown noise hasn’t been officially investigated much yet, but studies have shown that white noise improves sleep quality.
If you listen to brown noise to sleep, don’t set the volume too loud. Also, only listen to the sound for a short time. It’s a good idea to keep the lights off and the temperature cool, too.Finally, don’t worry if brown noise doesn’t work for you. What one person finds calming may be distracting to someone else!
