White noise is a random signal (or process) with a flat power spectral density. In other words, the signal contains equal power within a fixed bandwidth at any center frequency. White noise draws its name from white light in which the power spectral density of the light is distributed over the visible band in such a way that the eye's three color receptors (cones) are approximately equally stimulated.
Abstract
"On one hand white noise is a very simple process: it is stationary centered Gaussian, and it is independent at different moments of time. The combination of these properties singles it out as a natural object to start from: in a sense, white noise is a "universal" source of randomness, and as such it appears in many fields of applications." - Takeyuki Hida (Mathematician)

White noise is essentially the aural equivalent of the layer of visual discord I incorporate in my imagery.
