White noise

What is it ?

White noise is a type of noise that has a constant loudness across all frequencies. This means that white noise is made up of all audible frequencies equally. One can imagine white noise as being similar to a wall of sound, where every frequency is represented equally. White noise is used as a reference to measure the quality of information transmission in electronic and electrical communications, as well as to measure the absorption of materials and the reflection of surfaces in acoustics and physics.
