What is White Noise?

White noise is a random signal (or process) with a flat power spectral density. In other words, the signal contains equal power within a fixed bandwidth at any center frequency. White noise is considered “a-colored” or “colorless” because it contains equal power at all frequencies.

White noise is often used as a background sound to mask other sounds. It can be used to block out unwanted sounds from the environment, or to help you focus on a specific task. White noise can also be used to soothe and relax people who are anxious or stressed.

The term “white noise” comes from the fact that it is similar to white light, which contains all visible frequencies of light.
