The Federal Standard 1037C Telecommunications Glossary [1] [2] defines white, pink, blue, and black noise. The color names for these different types of sounds are derived from a loose analogy between the spectrum of frequencies of sound wave present in the sound (as shown in the blue diagrams) and the equivalent spectrum of light wave frequencies.
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 ...
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 ...
White noise devices are available from numerous manufacturers in many forms, for a variety of different uses, including audio testing, sound masking, sleep-aid, and power-napping. Sleep-aid and nap machine products may also produce other soothing sounds, such as music, rain, wind, highway traffic and ocean waves mixed with—or modulated by ...
You’ve probably heard of white noise. Now, other colors of noise like pink and brown are increasingly popular, especially on TikTok. ... "Different colors of noise have different strengths and ...
The smallest white noise machine on our list, this option has six different sounds to choose from. It can also be charged and used without a cord, making it easy to move around.

Also the slight rise in the white noise graph is attributed to it being a log rather than linear scale, but that can't be right, if it were on a linear scale it would surely slope downwards dramatically -- so it seems more like the slight rise is an aberration and this isn't true white noise (hardly surprising if it was generated from an OGG ...
