2. Pink noise - Wikipedia

   en.wikipedia.org/wiki/Pink_noise

   Pink noise, 1 ⁄ f noise, fractional noise or fractal noise is a signal or process with a frequency spectrum such that the power spectral density (power per frequency interval) is inversely proportional to the frequency of the signal. In pink noise, each octave interval (halving or doubling in frequency) carries an equal amount of noise energy.

4. Colors of noise - Wikipedia

   en.wikipedia.org/wiki/Colors_of_noise

   Pink noise spectrum. Power density falls off at 10 dB/decade (−3.01 dB/octave). The frequency spectrum of pink noise is linear in logarithmic scale; it has equal power in bands that are proportionally wide. [4] This means that pink noise would have equal power in the frequency range from 40 to 60 Hz as in the band from 4000 to 6000 Hz.

6. Noise generator - Wikipedia

   en.wikipedia.org/wiki/Noise_generator

   Zener diode based noise source. A noise generator is a circuit that produces electrical noise (i.e., a random signal). Noise generators are used to test signals for measuring noise figure, frequency response, and other parameters. Noise generators are also used for generating random numbers. [1]

7. Sound masking - Wikipedia

   en.wikipedia.org/wiki/Sound_masking

   Sound masking is the inclusion of generated sound (commonly, though inaccurately, referred to as "white noise" or "pink noise") into an environment to mask unwanted sound. It relies on auditory masking. Sound masking is not a form of active noise control (noise cancellation technique); however, it can reduce or eliminate the perception of sound ...

   WHAT IS PINK NOISE? You may have heard of white noise used to mask background sounds. The science is new with only a few small studies behind it, but that hasn’t stopped thousands of people from ...

9. Flicker noise - Wikipedia

   en.wikipedia.org/wiki/Flicker_noise

   Flicker noise is a type of electronic noise with a 1/f power spectral density. It is therefore often referred to as 1/ f noise or pink noise , though these terms have wider definitions. It occurs in almost all electronic devices and can show up with a variety of other effects, such as impurities in a conductive channel, generation and ...
