White noise (slang)

From Wikipedia, the free encyclopedia

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.

[edit] 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 was 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.
