[[Brownian noise]], also called Brown noise, is noise with a power density which decreases 6.02&nbsp;dB per octave (20&nbsp;dB per decade) with increasing frequency (frequency density proportional to 1/''f''{{i sup|2}}) over a frequency range excluding zero ([[direct current|DC]]). It is also called "red noise", with pink being between red and white.

Brownian noise can be generated with temporal [[Integral|integration]] of [[white noise]]. "Brown" noise is not named for a power spectrum that suggests the color brown; rather, the name derives from [[Brownian motion]], also known as "random walk" or "drunkard's walk".
