The big three in sleep sounds are white noise, brown noise, and pink noise, but there are many other noise types, including purple noise, gray noise, and even black noise (a.k.a. good ol ...
Brown noise: a relaxing rumble. Literally on another side of the spectrum from white noise lies brown noise (also called red noise.) “Brown noise accentuates lower frequencies, has a deeper ...

It is also called "red noise", with pink being between red and white. Brownian noise can be generated with temporal 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".
Brown noise can be produced by integrating white noise. [4] [5] That is, whereas white noise can be produced by randomly choosing each sample independently, Brown noise can be produced by adding a random offset to each sample to obtain the next one. As Brownian noise contains infinite spectral power at low frequencies, the signal tends to drift ...
White noise draws its name from white light, [2] although light that appears white generally does not have a flat power spectral density over the visible band. An image of salt-and-pepper noise In discrete time , white noise is a discrete signal whose samples are regarded as a sequence of serially uncorrelated random variables with zero mean ...
