What is white noise?Updated 2 months ago

White noise contains every frequency audible to the human ear in equal amounts, creating a humming sound. It often sounds like a high-pitched ‘shhh’, as our brain amplifies the higher-pitched region of the noise. White noise is considered soothing for some children and an effective tool for sleep, as it creates a constant background sound that helps to mask other disruptive sounds. People often liken white noise to the static that comes from an untuned radio or television. Learn more about white noise.
