Why is it called white noise?

2 Answers

White noise is so named because it's analogous to white light, which is a mixture of all visible wavelengths of light. Since it includes all audible frequencies, white noise is often used to mask other sounds.

White noise draws its name from white light. Similar to the way white light is a mixture of all visible wavelengths, white noise is a mixture of all audible frequencies.
