We all recognize the sound of a TV that “snow” or the sound of a fan, not only as the sounds of familiar household appliances, but also as what we say. “White noise”.

And if the term has moved from the science of physics to the writing concerns of Don DeLillo (and hopefully also to the directorial concerns of Noah Baubach), it does not have a monopoly on ambient sounds because they they also “come out” in other shades.

On a quick walk to tik tak, you will find that the hashtag #brown noise it’s not too much and not too little 86 million views. So what brown noise, how it differs from white and how it has become a useful tool in the hands of people with Attention Deficit Hyperactivity Disorder (ADHD)?

Bring to mind the sound of an airplane engine, lightning, or very strong wind. This is brown noise: wideband sound, that is, sound that is in the range of frequencies audible to the human ear, except that it uses lower frequencies than white noise and therefore produces a more bass sound, which sounds more pleasant to the ears of many.

Between these two noises now we also find it pink noise, which uses a combination of frequencies, with lower frequencies protruding – such sounds rain and rustle of leaves.

White, brown or pink noise can act as sound Camouflage Technique, as they can mask other annoying noises.

Of course for him Goran Sonderland, researcher at the University of Applied Sciences Western Norway, the effect of the above noises goes far beyond simple sound masking. He also conducted 15 studies on the effects of white noise on people with and without attention deficit hyperactivity disorder.

The results of his research are encouraging as to how white and brown noise can help people with the aforementioned disorder, as it turns out that these they do better on memory tests and language tests by listening to related sounds.

Everything is connected to her. dopamine. People with ADHD usually have lower levels of dopamine, but when listening to broadband sounds the brain begins to imitate the action of dopamine.

White or brown noise can eventually “tame” neurons a person with ADHD who often perceives stimuli erratically, but also help in concentration.

And the benefits of noise don’t stop there. According to a USC study, white and brown noise can help even those who don’t have ADHD, and in another study, Sunderland concluded that white noise also helps children with reading difficulties.

OUR Dan Berlo and a professor at Regis University, in turn, argues that white noise can work as an addition to those who need it. For example, Daniella Bloomer, who has ADHD and is struggling to pay for treatment, uses brown noise when she needs to focus, as does Taylor Griffin, who plays similar sounds while driving or cooking.

As for where you find white, brown or pink noise, YouTube as well as Spotify they are stocked with several lists that have what you are looking for, as well as related applications. It remains only to find the noise color that suits you.
