White noise is a type of sound that contains all audible frequencies played at the same intensity, creating a steady, uniform sound often described as a “static” or “shh” noise. It is commonly used to mask disruptive background noises, promote relaxation, and improve sleep quality. White noise helps by providing a consistent auditory environment, which can make it easier for individuals to fall asleep or concentrate in noisy settings. Similar sounds, such as pink noise or nature sounds, can also be used for similar benefits. White noise machines or apps are widely used for sleep, focus, and even stress reduction
