Have you ever wondered why the sound of rain feels so soothing? Or why does the sound of the waves constantly hitting the shore melt the juice in the ears?
The frequency of these sounds recently became a trend on ‘Tik Tok’ when users discovered ‘brown noise’ and lost its benefits which is the exact opposite of ‘white noise’.
Due to this trend, people are now turning to it to escape from the worries of modern life or to escape their inner feelings and thoughts for a few moments.
The sound is said to help people focus at work, sleep more easily, and make life easier for people with disorders like ADHD.
ADHD is called attention deficit hyperactivity syndrome.
But what is the secret of this sound and why has it become so famous?
What is brown noise?
In contrast to white noise, brown noise has more emphasis on the lower base tones that are audible to the human ear.
It can be heard all over the world while sitting on an airplane or in nature.
Importantly, the word brown is not a color but a reference to Brownian motion, the sound of pollen moving in water, which was first discovered by Robert Brown almost 200 years ago in 1827.
It is also known as red noise. Red noise has a lower frequency than white light.
Part of the reason for her rise in popularity is the ADHD community that helped her trend on social media.
Brown noise and neurodiversity
Psychologist Dr. Alex Dimitrio says that normal people are disturbed by all kinds of noise.
He told the BBC Newsday program that, on the other hand, the brain of people with ADHD works better under stress.
It is believed that gentle noise helps the brain to function better than complete silence.
Brown noise has been less studied than white noise, but research has shown that it is beneficial for people with ADHD.
TikTok user Natalia Bub, who suffers from ADHD, reacted to hearing brown noise for the first time.
He asked in surprise, “Is it real?” Where did my thinking go?’ In another video, he said, ‘It revolutionized my studies.’
Other colors of sound
There are also many other colors of sound that operate at different frequencies.
Apart from white, they have pink and violet colors. The only difference between them is the frequency.
Despite their benefits, not everyone can take advantage of them because for many it sounds like an annoyance.
“It’s a matter of personal choice,” says Dr. DiMetrio.
Infants are often soothed by listening to white noise because it is said to be similar to the sounds in the mother’s womb.
People who suffer from tinnitus, a condition in which there is constant ringing in the ears, may find comfort in violet noise.
Pink noise, which has a lower frequency than white noise but a higher frequency than brown noise, helps listeners fall asleep faster.
Despite claims of benefits attributed to all these sounds, scientists and experts disagree on their existence.
A 2020 review of 38 studies found limited evidence of a positive effect of white noise on sleep, with even less evidence for brown noise.
However, those who can benefit from this sound say that there is no doubt that it is beneficial.
A trick of the mind that can show you things that are not there
Why do we snore in our sleep and is it possible to stop this sound?
Cecelia Parker says she can concentrate by listening to the ambient sound of a coffee shop.
I hate silence because I have a lot to think about. “Brown noise from a coffee shop is good because it’s not identifiable and doesn’t have patterns.”
Data scientist Paz Bombo says he works to videogame soundtracks and sleeps to the sound of ocean waves. They say it made a positive difference to both their work and sleep.
“I usually listen to the sound of the ocean waves or a forest fire and fall asleep within 20 minutes.”
“I’ve also read that video game music helps work out, and it does.” Any sound that has repetition helps me focus.’
Alice Fonda Marsland is a native and mother-to-be. He says that ‘I had a sleeping problem and after giving birth, I couldn’t sleep at all.’
“Brown noise helped me a lot but unfortunately it didn’t help me sleep very long.”
Although the scientific factors behind it have not yet been proven, there is no doubt that brown noise is useful.
Alexia Troyan didn’t get much help when she was diagnosed with ADHD.
“I was told that if you lived with him for so long, the rest would pass, but they didn’t think that with life comes responsibilities.”
“I didn’t get any help but then I discovered sound therapy.”
She used to concentrate on work with drum music and now finds solace in Brown Noise.2.5: Noise Modeling – White, Pink, and Brown Noise, Pops and Crackles – Engineering LibreTextshttps://www.witpress.com/Secure/elibrary/papers/DN12/DN12001FU1.pdfhttps://faculty.washington.edu/seattle/gis129/575 copy/noise-pdf/noise.pdf
