|Risch  characterized purple noise by power density increasing 6 dB per |
octave with increasing frequency (density proportional to the square of frequency
). Lau, Arce, and Gallagher  defined green noise to be "the mid-frequency ...
|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

loudness curve, such as the inverse of the A-weighting curve, to give the
perception of equal loudness at all frequencies. Green noise really does exist,

inversion of the 1/f2 noise power spectrum, increasing its energy as its frequency
grows up proportionally is either labeled 'blue noise' (Wang 2008) or 'purple
|“When you get back to Houston, you can get white noise, black noise, purple |
noise and red noise, but this is God's country. There's nobody here but you and
