742. What is white noise? - AT
Acoustic "white noise" is a collection of random sounds that together have the same volume at every frequency or pitch. It's defined more accurately as having the same amount of power in each unit of its bandwidth, so that the acoustic power between 20 and 21 cycles per second is the same as the acoustic power between 500 and 501 cycles per second.
