Definition. Within the scientific literature, the term 1/f noise is sometimes used loosely to refer to any noise with a power spectral density of the form. where f is frequency, and 0 < α < 2, with exponent α usually close to 1. One-dimensional signals with α = 1 are usually called pink noise.

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 is inversely proportional to the frequency of the signal. In pink noise, each octave interval carries an... Wikipedia
