Understanding Plain White Noise: What It Is and How It's Used

White noise derives its name from a combination of different frequencies of sound, much like the color white is made up of a combination of various colors of light. By definition, white noise is a consistent sound generated across all hearing ranges. This even distribution of sound makes it extremely effective in masking other noises, leading to its popularity in helping people relax, concentrate, sleep, or improve focus. White noise has been compared to the sound of a waterfall or fan, a soothing, constant acoustic experience that can significantly aid in stress reduction. The use of white noise machines, smartphone apps, and websites has become increasingly popular among those looking for a more peaceful environment. Additionally, white noise is often incorporated into audio recording and testing processes due to its ability to minimize background noise.
