Pink noise, 1⁄f noise, fractional noise or fractal noise is a signal or process with a frequency spectrum such that the power spectral density (power per frequency interval) is inversely proportional to the frequency of the signal. In pink noise, each octave interval (halving or doubling in frequency) carries an equal amount of noise energy.
Pink noise sounds like a waterfall.[2] It is often used to tune loudspeaker systems in professional audio.[3] Pink noise is one of the most commonly observed signals in biological systems.[4]
The name arises from the pink appearance of visible light with this power spectrum.[5] This is in contrast with white noise which has equal intensity per frequency interval.
