White noise is called so because it comprises a wide range of sound frequencies played together at equal intensity, similar to how white light contains all visible colors blended together. This uniform distribution of sound frequencies creates a consistent, steady noise that can mask other sounds, making it useful for promoting relaxation or aiding sleep. The term "white" is borrowed from optics, reflecting the idea of combining multiple elements into a single, cohesive output.
So called "White Noise" is purely random. Noise that you hear that comes from from physical processes almost always has a pattern and is not white noise.
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.
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).

White Noise Records was created in 1978.
Sound of White Noise was created in 1993.
The duration of White Noise - film - is 1.68 hours.

Noise canceling headphones use neither white noise nor music. True noise canceling headphones use microphones that pick up outside sounds, amplifiers to invert those sounds, and combining circuits to combine the signal to be played with this inverted external sounds before feeding it to the speakers. The external noise vanishes by cancellation, which is why they are called "noise canceling".
White noise is also called "snow" and it looks like a snow storm on the screen. It is the result of an analog receiver not getting a signal and it can be compared to the hiss from a radio when it loses its signal. Modern televisions often suppresses the noise and digital televisions do not suffer from it at all.
