a mixture or random noise sounds extending over the entire audible frequency spectrum with approximately equal intensity at all frequencies. It is used in certain experiments, as in psychology, to prevent subjects from hearing meaningful sounds.
A sound produced by combining sounds of all different frequencies together. Many surround sound receivers use white noise for speaker calibration. The sound is played through one speaker at a time, and receiver settings can be changed until all of the speakers produce the same volume level at the listening position.
A random noise that contains an equal amount of energy per frequency band. That is, 100-200, 800-900, and 3000-3100. Pink noise has an equal amount of energy per octave. The bands 0-200, 800-1600, and 3000-6000 all contain the same amount of energy.
Random noise with equal energy per frequency is called white noise. It tends to sound very bright and "hissy" due to our ears frequency response curve. (Each ascending octave contains twice as many frequencies as the next lower one, so there is a significant "build up" of energy in the higher octaves.)
Noise having a frequency spectrum that is continuous and uniform over a specified frequency band. Note: White noise has equal power per hertz over the specified frequency band. Synonym: additive white gaussian noise.
Noise with random amplitude (strength) over a wide frequency range. Used to test speakers for resonance and sensitivity. Low levels of white noise can be used to cover up other random noises, for example, in an open office environment.
White noise is a random signal (or process) with a flat power spectral density. In other words, the signal's power spectral density has equal power in any band, at any centre frequency, having a given bandwidth. White noise is considered analogous to white light which contains all frequencies.
White Noise is the eighth novel by Don De Lillo, and is an example of postmodern literature. Widely considered his "breakout" work, the book won the National Book Award in 1985 and brought him to the attention of a much larger audience.
White Noise is a 2005 drama/supernatural horror film, directed by Geoffrey Sax and produced by Brightlight Pictures. The title refers to electronic voice phenomena (EVP), where voices, which some believe to be from the "other side," can be heard on audio recordings. The film is not related to the postmodern novel White Noise by Don De Lillo.
White Noise is an electronic music band formed in London, England in 1969 by American born David Vorhaus B.Sc, Dip. Elec, a classical bass player with a background in both physics and electronic engineering. He was initially joined by BBC Radiophonic Workshop composers Delia Derbyshire and Brian Hodgson, both ex of electronic music project Unit Delta Plus.
