In signal processing, white noise is a random signal having equal intensity at different frequencies, giving it a constant power spectral density. The term is used, with this or similar meanings, in many scientific and technical disciplines, including physics, acoustical engineering, telecommunications, and statistical forecasting. White noise refers to a statistical model for signals and signal sources, rather than to any specific signal. White noise draws its name from white light, although light that appears white generally does not have a flat power spectral density over the visible band.

In this case our application shows white sound that comes from the elements of nature such as rain, animals or thunder. But it also comes from specific objects such as airplanes and fans that generate a static sound wave that in most cases serve to relax and help concentration.

The App is very simple to use. You have four classes inside the app. These are:

- Black screen: A permanent sound frequency.
- Combined natural sounds: Shows dozens of natural sounds that can be combined with each other to generate the sound you want and with which you feel comfortable.
-White sounds of nature already generated: A collection of the best white sounds for different functions, relaxation, concentration, study, falling asleep and meditation.
- Finally a collection of natural sounds of water and bamboo for maximum relaxation against stress and anxiety

You can enjoy this app with all content that we have created for you.
