The concept of “white noise” seems to be more popular, an indeterminate sound that presupposes the absence of silence but at the same time produces a diffuse crackle associated with radio signal interference, a murmur where all sound frequencies seem to be present at the same time without emphasizing anything, is special. Something that some people use apps to calm and put babies to sleep, for example.
Brown noise is characterized by the predominance of the lowest, deepest sound frequencies.
And all of a sudden there seems to be a fever in TikTok for the «brown sound» that is to gain expectation and presence in the videos posted on this network. From those who have just discovered it to those who claim it has “changed their lives,” what is this “brown sound” and what effects does it produce?
We must start by defining that the essential characteristic of this so-called “brown noise” is the predominant presence (if not the only one) of the lowest sound frequencies, corresponding to the deepest sounds. By eliminating (or reducing to the maximum) the highest notes, which correspond to the highest sound frequencies, a sound is obtained that enables deep and calm resultswhich can invite relaxation.
Some examples of sounds from nature where this “brown sound” predominates are storms, thunder, or the sound coming from streams with a fast flowing stream of water between rocks, or the waterfalls themselves.
As for the pure nomenclature, curiously, the “brown” noise is not specifically related to the color, but to the surname of Robert Brown, a Scottish botanist who discovered in 1827 by analyzing microscopic pollen particles the so-called brown wrinkle, characterized by its low frequency, equivalent to the most serious sounds of the acoustic spectrum. Since his last name is the same word used in English for the color brown, hence the name “brown noise”.
When we talk about “white noise”, a nominative pattern is followed that is inspired by chromatography, as the white color would be the sum of all colors while white noise would be the sum of sounds of all frequencies.
Once the origin of the name and the nature of the sound is known… why is it all the rage on TikTok right now? There are several universities (the Department of Cognitive Science at Lund University in Sweden, the Department of Psychology at New York University…) that have studied the benefits of listening to “white noise” on the cognitive performance of those who listen to it. , especially in those that have ADHD characteristics (Attention Deficit Hyperactivity Disorder). And something similar seems to be happening among those who listen to ‘brown noise’.
Some of these people share their personal experiences after hearing “brown noise” through TikTok, in addition to posting videos with these types of sounds. Among the advantages described are the: increased productivity, improved concentration and achieving a state of well-being and tranquility. Not only while listening to the sound, but the effect remains after.
