actually noise suppression systems arent called "white noise" any longer...thats the label for things like mechanical diffusers etc...when a noise suppression system is installed its "usually" called ....Pink Noise!! LOL
White noise has also been used in electronic music, where it is used either directly or as an input for a filter to create other types of noise signal. It is used extensively in audio synthesis, typically to recreate percussive instruments such as cymbals which have high noise content in their frequency domain.

this is nothing like Red or Brown noise either..
For the guitar tone, see Brown sound. For the defecation-inducing sound, see Brown note.
In
science,
Brownian noise (or
Brown noise or
red noise) is the kind of
signal noise produced by
Brownian motion. It is named not for a color, but in honor of
Robert Brown, the discoverer of Brownian motion.
