Thermal noise occurs due to the motion of millions of electrons in a object. Due to the central limit theorem, the total effect can be modeled as a Gaussian distributed random variable with zero mean and N_0/2 variance.

It has to do with data communication. It is called the Shannon channel capacity theory where double the bandwidth equals double the highest data rate. This is of course theoretically and does not take into account white noise (thermal noise), impulse noise, attenuation distortion or delay distortion.

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.
1. Shot or Schottky noise 2. Thermal or Johnson noise 3. Partition 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.
Decible(dB)
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).
It is the bandwidth, the temperature, and the resistance. Look at the link: "Calculation of Noise voltage: Thermal noise".
The Production Budget for White Noise was $10,000,000.
White Noise Records ended in 2003.
White Noise Records was created in 1978.
