|It is also known as 'differentiated white noise' as a differentiator circuit has a |
frequency response rising at 6 dB per octave. It is sometimes called purple noise.
It has no known audio use. Grey noise is pink noise modified by a
|The opposite of brown noise is 'purple' noise, which increases power per octave (|
also by 6 dB). 'Grey' noise exploits a psychoacoustic loudness curve to deliver a
more accurate perceptual white noise to the listener. So-called 'black' noise ...
|The background noise of the world is sometimes referred to as green noise. |
frequency range is called blue noise purple noise. Asound that is equally loud at
all frequencies is called gray noise brown noise. A noise capable to canceling
|It would not look brown in the visual spectrum, the name comes from the |
Brownian motion. Blue noise is the opposite to pink noise, in that it has a power
density of +3dB per octave. Purple noise is the opposite to brown noise, in that it
has a ...
|Figure 2.17 Blue noise also emphasizes the higher frequencies, but the drop in |
amplitude at lower frequencies is not as extreme as violet noise. frequency

frequency doubles, its power spectrum density increases by 6dB, which means
that the energy is proportional to f 2: the higher the frequency the greater the
