In signal processing, white noise is a random signal with a constant power spectral density.

The term is used, with this or similar meanings, in many scientific and technical disciplines, including physics, acoustic engineering, telecommunications, statistical forecasting, and many more. White noise refers to a statistical model for signals and signal sources, rather than to any specific signal.

In discrete time, white noise is a discrete signal whose samples are regarded as a sequence of serially uncorrelated random variables with zero mean and finite variance; a single realization of white noise is a random shock. 
White noise draws its name from white light, although light that appears white generally does not have a flat spectral power density over the visible band.
Music
White noise is commonly used in the production of electronic music, usually 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 or snare drums which have high noise content in their frequency domain.
White noise may be generated digitally with a digital signal processor, microprocessor, or microcontroller. Generating white noise typically entails feeding an appropriate stream of random numbers to a digital-to-analog converter. The quality of the white noise will depend on the quality of the algorithm used.

White Noise explores several themes that emerged during the mid-to-late twentieth century, e.g., rampant consumerism, media saturation, novelty academic intellectualism, underground conspiracies, the disintegration and reintegration of the family, human-made disasters, and the potentially regenerative nature of human violence. The novel's style is characterized by a heterogeneity that utilizes "montages of tones, styles, and voices that have the effect of yoking together terror and wild humor as the essential tone of contemporary America."

Ecocritic Cynthia Deitering had described the novel as central to the rise of "toxic consiousness" in American fiction in the 1980s, arguing that the novel "offers insight into a culture's shifting relation to nature and to the environment at a time when the imminence of ecological collapse was, and is, part of the public mind and of individual imagination".
