A white noise machine is a device that produces a sound that is random in character, which sounds like a rushing waterfall or wind blowing through trees. Often such devices do not produce actual white noise, which has a harsh sound, but more often pink noise, whose power rolls off at higher frequencies, or other colors of noise.
