In simple terms, white noise is a special type of sound signal which is used to mask background sounds. When used to promote healthy sleep, white noise helps to drown out sounds which might otherwise prevent you from either falling asleep or waking up whilst asleep.

Similarly, it is asked, what is the frequency of the white noise?

White noise is a sound that contains every frequency within the range of human hearing (generally from 20 hertz to 20 kHz) in equal amounts. Most people perceive this sound as having more high-frequency content than low, but this is not the case.

What is a white process?

A white noise process is a random process of random variables that are uncorrelated, have mean zero, and a finite variance. Formally, is a white noise process if.

Why is it called the white noise?

This kind of minimum-information noise is called white noise, by analogy with white light which is a uniform mixture of all the different possible colors. In the frequency (Fourier) analysis often used in signal processing, white noise is a uniform mixture of random energy at every frequency.
