Relax and focus better by adding white noise to your MP3s

Many users may not be aware of the benefits of white noise, a constant sound that helps many people reduce stress and relax and that we can create ourselves using the right tools.

What is white noise and what is it for?

We are talking about a noise formed by a random signal that contains all the frequencies and these are of the same power, establishing their signal values ​​in two different times that do not keep statistical correlation. As a consequence, its power spectral density is constant and therefore its graph is flat. This means that it is a monotonous and constant sound that masks the rest of the ambient noises, so it is very easy to get used to them as they have the same power and loudness.

Examples of white noise can be found in the sound of the sea breaking, raindrops, a television turned on with the volume low, etc. There are many people who love white noise since it usually helps them to relax or focus. It can also help us to block all other sounds that occur in the environment and even help them sleep, due to its ability to mask other sounds. Beyond being a placebo effect, the efficacy of white noise to relax us and even promote the degree of attention is corroborated by hearing experts.
