Brownian noise is a random signal that has been filtered in order to generate a lot of energy at low frequencies. Its power density is inversely proportional to f^2 and decreases by 6 dB per octave. Brownian noise produces a much warmer tone than white noise (0 dB/oct) or pink noise (-3 dB/oct). In audio applications, Brownian noise is used to check subwoofer phase issues. To properly integrate...

In signal processing, white noise is a random signal having equal intensity at different frequencies, giving it a constant power spectral density. The term is used with this or similar meanings in many scientific and technical disciplines, including physics, acoustical engineering, telecommunications, and statistical forecasting. White noise refers to a statistical model for signals and signal ...
