Noise is a random signal that does not have a distinct pitch, such as hissing, breath noise, or the sound of wind or the surf. Noise is often described by different “colors” such as white, pink, red, or blue which have different frequency distributions. White noise has equal power per unit of frequency (such as every 1000 hertz), resulting in a brighter, hissier sound.
