Can brown noise turn off your brain?

Is there any evidence that sound therapy can help with ADHD?

dr. Soderlund and other researchers have studied the benefits of white noise for children with reading difficulties and ADHD. In one experiment, children with reading difficulties completed a 30-minute test that involved reading and memorizing words; those listening to white noise through headphones generally outperformed the test.

The sound allows them to focus better, said Dr. Soderlund, and to perform academic duties.

That may be because, in people with ADHD, the brain’s prefrontal cortex may have trouble filtering the stimuli a person encounters in a particular environment, such as chatter from a nearby conversation or an image passing across someone’s screen. else flashes, said Dr. bains .

Those with ADHD may not have enough dopamine in their brains, a chemical that affects attention and motivation, said Dr. diaz. Without enough dopamine, the brain remains “hungry” as you try to concentrate, explained Dr. Diaz out. “While one part of the brain is trying to concentrate, the other part of your brain is looking for food.” When you listen to a sound like brown, pink, or white noise, “you almost call the circuits a task,” she said. “‘You listen to this while I focus on this task.'”

What about sound therapy and sleep?

Scientists have come to conflicting conclusions about whether a certain type of sound can help you sleep better. A 2020 review of 38 studies found limited evidence that: white noise may improve sleep, despite the prevalence of white noise machines marketed for healthier nights. Some companies promote white noise machines to help babies sleep, claiming that the sound mimics the environment in the womb.

Few studies have explored the use of brown noise as a sleep aid, although one of the claims circulating around TikTok is that it can help you drift off.

Ten years ago, a group of researchers conducted a small study where they asked 40 participants to listen to a steady stream of pink noise while they slept all night. By looking at the participants’ brainwaves, the researchers saw that those who listened to pink noise slept more deeply, with less complex brainwaves and better responses to sleep disturbances compared to when they slept without the noise.

dr. Berlau pointed to a simple theory of why people say sound causes sleep — whether it’s pink, white, or some other shade. Noises can shut out your downstairs neighbor, traffic and your partner’s snoring.

And, experts said, if any form of sound therapy works for you, it can’t hurt to use it.

There is probably no danger when listening to brown sound for, say, eight hours at a time, said Dr. Berlau, unless someone plays the sound at unsafe volumes (listening to sound above 70 decibels for a long time can damage your hearing).

Meanwhile, there are those who cherish the noise.

“When you find that happy place — a calm, quiet, consistent brain,” said Dr. Diaz, “it feels so blissful.”
