White noise draws its name from white light, [2] although light that appears white generally does not have a flat power spectral density over the visible band. An image of salt-and-pepper noise In discrete time , white noise is a discrete signal whose samples are regarded as a sequence of serially uncorrelated random variables with zero mean ...
White Noise is the eighth novel by Don DeLillo, published by Viking Press in 1985. It won the U.S. National Book Award for Fiction. [1] White Noise is a cornerstone example of postmodern literature. It is widely considered DeLillo's breakout work and brought him to the attention of a much larger audience.
It is also known as differentiated white noise, due to its being the result of the differentiation of a white noise signal. Due to the diminished sensitivity of the human ear to high-frequency hiss and the ease with which white noise can be electronically differentiated (high-pass filtered at first order), many early adaptations of dither to ...
Acoustics is the interdisciplinary science that deals with the study of mechanical waves in gasses, liquids, and solids including vibration, sound, ultrasound, and infrasound. A scientist who works in the field of acoustics is an acoustician , while someone working in the field of acoustical engineering may be called an acoustical engineer . [ 3 ]
Only when the intensity of the noise replacing the phonemes is the same or louder as the surrounding words, does the effect properly work. This effect is made apparent when listeners hear a sentence with gaps replaced by white noise repeat over and over with the white noise volume increasing with each iteration.

The term uncorrelated noise refers to a noise source being uncorrelated to a signal or another noise source. [1] White noise in particular, due to its randomness, is uncorrelated to any other signal and is also serially uncorrelated (i.e., later values of it have no correlation to earlier values).
First, white noise is a generalized stochastic process with independent values at each time. [12] Hence it plays the role of a generalized system of independent coordinates, in the sense that in various contexts it has been fruitful to express more general processes occurring e.g. in engineering or mathematical finance, in terms of white noise.
