Randomness that is distributed uniformly.
Noise that has equal energy at each frequency.
A random energy where there is an energy distribution so that the amount of energy is the same for each cycle, causing the noise level to increase with frequency.
A signal composed of all frequencies, which vary randomly in phase, each frequency having equal long-term energy levels.
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.
Noise that results from the random motions of electrons in electronic materials. Also known as average white Gaussian noise.
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.
Acoustical or electrical noise of which the intensity is the same at all frequencies within a given band.
An audio signal with equal energy at all frequencies. Has more energy at higher frequencies than pink noise from the way octaves are related to frequencies. see also pink noise
A random noise component which increases in level with frequency.
a `sh' noise produced by a stimulus containing all audible frequencies of vibration
an annoying sound, although it is sometimes created for test purposes
A hiss-like sound formed by combining all audible frequencies; used in the ganzfeld experiment.
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.)
A random signal with an energy distribution that produces the same amount of noise power per Hz.
Random Noise having a continuous spectrum and constant energy per cycle. Compared to pink noise, white noise sound bright. See: Pink Noise
contains equal amounts of all audible frequencies at every frequency there is the same amount of power
A full audio spectrum signal with the same energy level at all frequencies. White noise has much more treble energy than pink noise.
heterogeneous mixture of sound waves extending over a wide frequency range that may be used to mask unwanted noise that may interfere with sleep
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.
A hiss-like sound, formed by combining all audible frequencies. Often used as a background to EVP recordings.
sound or electromagnetic wave whose spectrum is continuous and uniform as a function of frequency.
The audio equivalent of Brownian motion. Sounds that are unrelated and sound like a hiss. The video equivalent of white noise is "snow" in television reception.
This is technically sound with a uniform frequency spectrum over a wide range of frequencies. Non-technically, white noise is any unobtrusive background...
Completely random and uncorrelated noise, with equal power at all frequencies. [Silk90
A hiss-like sound, formed by compiling all audible frequencies (used in Ganzfield experiments).
Background noise generated by a random-frequency noise generator to mask high-frequency sounds, particularly consonants in human speech. See also Sound Masking.
A mixture of sound waves extending over a wide frequency range that may be used to mask unwanted noise that interferes with sleep. Also called white sound.
Similar to pink noise, except that white noise contains equal energy at each frequency point. See also Pink noise
Noise with constant energy per unit bandwidth that is independent of the central frequency.
Noise in which a constant energy level per unit (1 Hz) is maintained in all frequencies.
a test signal comprising random noise, providing constant energy at all frequencies, similar to the sound heard when an FM radio is set between stations.
Broadband pseudo-random signal with uniform power in each frequency band
A random, undifferentiated signal having equal energy content at all frequencies. Generally used for test purposes. White noise sounds like the speech sibilant "ss".
Noise of uniform power over a wide range of frequencies.
Random noise that has uniform power spectral density at every frequency in the range of interest.
A complex sound in which all frequencies of the audio spectrum are present. A waterfall produces a good representation of white 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 the heterogeneous mixture of sound waves expanding over a wide frequency range that may be used to mask unnecessary noise that may obstruct with sleep
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.
