This is just a guess, but i think it is because the color white is a mixture of frequncies of light ranging from red to violet, so if you look at the wave pattern, it will look like a complete mess. By contrast, a single colour will have a nice neat wave pattern. Therefore, i would assume that "white" is used as a metaphor for a wave which consists of a mixture of lots of different frequencies. White light is the combination of all visible frequencies of light, white noise is the combination of many (but not all) audible frequencies of sound.
White noise sounds like a hiss. It can be used in the sythesis of musical instruments or sound effects. It is random noise and can be used for signal analysis.
White noise. A more general term would be "ambient sound" or "ambient noise", which may or may not be white noise. White noise is the combination of every sound frequency and so it is analogous to the color white, a mixture of all of the different frequencies of visible light. White noise is usually called static.
Ambiance, or Ambient Sounds White Noise
A white noise machine of generator has one standard use. It is used for sufferers of tinnitus (who experience a constant ringing in their ears) to mask their symptoms.
"Pure white noise" refers to random patternless noise, often used to mask other sounds. "Pure White Noise" is also the name of a company that sells such products, including a 74-minute audio CD. White noise may be used to mask distracting sounds when trying to sleep or to prevent eavesdroppers from hearing a discreet conversation.
A Gaussian noise is a type of statistical noise in which the amplitude of the noise follows that of a Gaussian distribustion whereas additive white Gaussian noise is a linear combination of a Gaussian noise and a white noise (white noise has a flat or constant power spectral density).
A white noise maker is often used to help people fall asleep. A common form of white noise is static from a television channel. Many times people fall asleep to that kind of static.
Squawking
White noise can be used to disorient individuals prior to interrogation and may be used as part of sensory deprivation techniques. White noise machines are sold as privacy enhancers and sleep aids and to mask tinnitus. White noise CDs, when used with headphones, can aid concentration by masking irritating or distracting noises in a person's environment. In open plan offices, large corporations such as ExxonMobil apply white noise to reduce the reach of speech, thus, by preventing office staff from being distracted by conversations in the background, safeguarding productivity.
