Why can 'white noise' help us sleep better?

A device that produces white noise (White Noise) is the simplest solution to prevent other noises from affecting you. Other sounds will be blocked by white noise before reaching your ears. Want to sleep better? The solution is simple: create a mixture of noise types.

Not only do many people find themselves unable to sleep without turning on their fans, many companies sell devices that make sounds that help you sleep better. So what's going on between your brain and ears?

In short, white noise is better than other noise. At least it really works for many people.

White noise is a collection of noise that emits steadily on all human audible frequencies.(Photo: Beate Firlinger).

White noise, also known as white noise or white noise , is technically defined as a collection of noise that emits at regular intervals on all human audible frequencies. If you are a musician, to play a C-note, you need to play a sound with a frequency of about 261.6 Hz. White noise is produced by sounds of equal intensity at low to high frequencies that can be heard by humans. If explained in terms of music, the white noise generated from a giant band playing the notes are not too different with equal pitch at the same time. Machines that can make these sounds very well, such as fans.

When you are awakened by a sound in the middle of the night, it is not actually because of that noise but because of a sudden change or difference between that sound and the other sounds you are listening to while you sleep. .White noise creates a wall effect, it blocks all the sudden differences in sound that can disrupt sleep or make you sleepless. Seth S. Horowitz, a neuroscientist, said, "You can still hear it while you sleep."

"This is the reason most of us can sleep easily with white noise generated regularly by CPAP breathing machines instead of the random snoring of people lying nearby," said Clete A. Kushida, director of the Center. Sleep research in Stanford people, said.

Another type is called pink noise . Basically, pink noise is white noise but the frequency is inversely proportional to intensity . White noise has equal intensity at all frequencies; Pink noise emits louder and enters lower notes in the range. Pink noise is more effective for people with tinnitus or those who feel the high pitched noise of white noise is uncomfortable for them. In addition, there is Brown noise (Brown is the name of the person, not the color), violet noise and many other colors with different characteristics. Each person will suit a different type of sound.

And of course not everyone needs these sounds to be able to sleep easier. For some people, the white wall noise effect is the exact opposite, making them more sensitive to other sounds, Horowitz said.

There are cases of random additive that makes some people better able to record sound in an environment with white noise compared to a completely silent environment. But maybe we will explain this later, after reading this article, you probably need a little rest!
