ABOUT THE AUTHOR
Mike Coviello (Tanner) is a former aerospace engineer who specialized in hypergolic propellants. His hobbies include shooting zombies and reloading ammunition.
Also known as "1/f", "random walk", "drunkard's walk" ,"red" and "Brownian". It is white noise that has been filtered to contain an approximately equal amount of energy in each octave. When compared to white, pink is much more pleasing to the ear, and sounds closer to natural sounds such as wind or ocean surf. It is generally considered the kind of noise that is most prevalent in nature.
More About Pink
Pink is a variant of white. It is white noise that has been filtered to reduce the volume at each octave. This is done to compensate for the increase in the number of frequencies per octave. Each octave is reduced by 6 decibels, resulting in a noise sound wave that has equal energy at every octave. Source: searchcio-midmarket.techtarget.com
It also contains the wide range frequency signal in the spectrum and is commonly found in nature environment. Unlike white noise, listening to pink noise is more comfortable. The sound is quite similar to ocean. Some people play it in the office for relaxation and concentration. Source: burninwave.com
Pink is identical to white except the higher frequencies have been turned down. This creates a kind of noise that sounds a little lower in pitch, which some people find to be more soothing than white noise. Source: thewhitenoisealbum.com
White noise is a sound that contains every frequency within the range of human hearing (generally from 20 Hz to 20 kHz) in equal amounts. Most people perceive this sound as having more high-frequency content than low, but this is not the case. This perception occurs because each successive octave has twice as many frequencies as the one preceding it. For example, from 100 Hz to 200 Hz, there are one hundred discrete frequencies. In the next octave (from 200 Hz to 400 Hz), there are two hundred frequencies. White can be generated on a sound synthesizer. Sound designers can use this sound, with some processing and filtering, to create a multitude of effects such as wind, surf, space whooshes, and rumbles. Pink is a variant of white noise. Pink is white that has been filtered to reduce the volume at each octave. This is done to compensate for the increase in the number of frequencies per octave. Each octave is reduced by 3 dB, resulting in a noise sound wave that has equal energy at every octave. Source: iroi.seu.edu.cn
This web page is all about pink noise, what it is, what it sounds like and where you can buy it. Anyone that wants to hear what it sounds like can simply open this web page on the internet. As the page opens a sound file (wave file) plays a continual sound of pink. The file is looped to play continually until the page is closed. The listener adjusts the sound with the volume controls on their computer.
