White Noise (slang)

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.
