White noise (slang)

The term white noise, the 'sh' noise produced by a signal containing all audible frequencies of vibration, is sometimes used as slang (or a neologism) to describe a meaningless commotion or chatter that masks or obliterates underlying information.

The information itself may have characteristics that achieve this effect without the need to introducing a masking layer. A common example of this usage is a politician including more information than needed to mask a point he doesn't want noticed.

In music the term is used for music that is discordant with no melody; disagreeable, harsh or dissonant.

"White noise" in the media

On the January 11, 2005 broadcast of ABC's Good Morning America, Claire Shipman claimed "the political rhetoric on Social Security is white noise" to most Americans.

The novel White Noise by Don DeLillo explores several themes that emerged during the mid-to-late twentieth century. The title is a metaphor pointing to the confluence of all the symptoms of postmodern culture that in their coming-together make it very difficult for an individual to actualize his or her ideas and personality.

White noise

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. Depending on the context, one may also require that the samples be independent and have the same probability distribution (in other words i.i.d is a simplest representative of the white noise). In particular, if each sample has a normal distribution with zero mean, the signal is said to be Gaussian white noise.

The samples of a white noise signal may be sequential in time, or arranged along one or more spatial dimensions. In digital image processing, the pixels of a white noise image are typically arranged in a rectangular grid, and are assumed to be independent random variables with uniform probability distribution over some interval. The concept can be defined also for signals spread over more complicated domains, such as a sphere or a torus.

In music

New Slang

"New Slang" is a song by American rock band The Shins, released on February 19, 2001 as the lead single from the group's debut studio album, Oh, Inverted World (2001). Written by guitarist and vocalist James Mercer, it concerns his hometown of Albuquerque, New Mexico and his experiences there in his late twenties. The lyrics are fueled with "angst and confusion," as Mercer was finding himself constantly depressed and disconnected from his friends and scene. The song attracted attention from Sub Pop Records, who issued the song as a single in February 2001. The buzz created by the song led to positive press for the group's debut album, Oh, Inverted World.

The song began to be licensed in a variety of media beginning in 2002, including various television programs and a McDonald's advert that aired during the 2002 Winter Olympics. Although the song never charted on any international charts, it became a sensation following its appearance in the film Garden State (2004), where a character referred to it as a song that "will change your life." The band saw increased record sales and notoriety as a result. Critics were very positive in their assessments of "New Slang", with many calling it one of the best songs from Oh, Inverted World.

Noise

Noise is a variety of sound. It means any unwanted sound. Sounds, particularly loud ones, that disturb people or make it difficult to hear wanted sounds, are noise. For example, conversations of other people may be called noise by people not involved in any of them; any unwanted sound such as neighbours playing loud music, portable mechanical saws, road traffic sounds, or a distant aircraft in quiet countryside, is called noise.

Acoustic noise can be anything from quiet but annoying to loud and harmful. At one extreme users of public transport sometimes complain about the faint and tinny sounds emanating from the headphones or earbuds of somebody listening to a portable audio player; at the other the sound of very loud music, a jet engine at close quarters, etc. can cause irreversible hearing damage. At intermediate levels there are a range of deleterious health effects from noise. This "intolerable corruption of human space" can be called noise pollution. A claim made by Luigi Russolo in his article, The Joys of Noise is that noise has become so prominent that pure sound no longer exists.
