White noise refers to a type of sound or signal that contains all frequencies within the audible range, played at equal intensity. It sounds like a constant, uniform "hiss," similar to the noise of static on a radio or the sound of a fan. White noise is often used to mask other sounds, helping people concentrate or sleep by creating a consistent background noise. It is called "white" because, like white light, it combines all the frequencies in the spectrum. White noise is also used in various fields like audio testing or soundproofing.White noise refers to a type of sound or signal that contains all frequencies within the audible range, played at equal intensity.
