	Colors of noise - Wikipedia, the free encyclopedia
		White noise is a signal (or process) with a flat frequency spectrum in linear space.
		Oceanic ambient noise (that is, noise from distant sources) is often described as "red" due to the selective absorption of higher frequencies by the ocean.
		Orange noise is quasi-stationary noise with a finite power spectrum with a finite number of small bands of zero energy dispersed throughout a continuous spectrum.

	Equalization of Sound Systems
		Typically, white noise or pink noise is used.
		White noise is noise whose amplitude is constant throughout the audible frequency range.
		Pink noise is often the choice for equalizing auditoriums.

	Pink noise - Wikipedia, the free encyclopedia
		), also known as 1/f noise or flicker noise, is a signal or process with a frequency spectrum such that the power spectral density is proportional to the reciprocal of the frequency.
		One important parameter of noise, the peak versus average energy contents or the crest factor, cannot be specified for pink noise, because it depends on f
		Pink noise is also found in many electrical readings of the human brain.

	epanorama.net/Noise types (Site not responding. Last check: 2007-08-20)
		White noise is noise in which the intensity of the power spectral density is constant and independent of frequency.
		Pink noise is the common name given to 1/f noise which crops up in many natural stochastic processes and approximates the power spectrum of music signals too.
		pink noise filters are a little harder to design but i had posted a design that requires 3 poles and 3 zeros that seems to do okay.

	Pink Noise (Site not responding. Last check: 2007-08-20)
		Pink noise (AKA 1/f noise or flicker noise) is similar to white noise except that it contains an equal amount of energy in each octave band.
		Pink noise can be generated by putting white noise through a pinking filter which removes more energy as the frequency increases (approximately 3 dB per octave).
		As white noise is anagous to white light (representing all frequencies equally), pink noise is anagous to light which tends towards the lower end of the visible light spectrum (red light).

	Hyperacusis Network > White Noise/Pink Noise?
		Pink noise is very similar to White noise, but with the amplitude decreasing with frequency at a constant rate per octave (3db).
		Pink noise closely matches the spectrum of sound that we hear in our everyday world.
		Even for people who say they can't tolerate the sound of pink noise are still taking in the sound of human voices and everything else that goes with life.

	Pink Noise press
		Pink Noise is a local art rock quartet who strives to keep their audience guessing.
		Standing on the shoulders of bands like the Pixies and fellow NYC groundbreakers Sonic Youth, Pink Noise don't rely on any infectious pop hooks or catchy dance beats.Instead their latest LP, "All Is Nu", produces a tremulous vibe, a feeling, a notion simoultaneously disarming and eerie.
		By the third song, “Bland,” you have a fairly strong grasp of Pink Noise’s low-energy art rock – that meanders along and is punctuated by yelps and screams of anguish.

	DSP Generation of Pink Noise
		Pink noise has the same distribution of power for each octave, so the power between 0.5 Hz and 1 Hz is the same as between 5,000 Hz and 10,000 Hz.
		The most obvious use of pink noise is as an audio signal, to be used directly, to be filtered or to be used to modulate something.
		It is possible to conceive of a pink noise generator with "k" rate control of level, upper and lower boundary frequencies and the slopes of those boundaries.

	Pink Noise Generator for Audio Testing (Site not responding. Last check: 2007-08-20)
		White noise (the sound you hear when a TV is tuned to a non-existent station) has a frequency characteristic which raises the power level by 3dB with each increasing octave, and is not suitable for response testing (and will probably blow your tweeters as well).
		By combining a 3dB / octave filter and a white noise source, we can get a very good approximation to "perfect" pink noise, where the power in the octave (for example) 40 to 80Hz is exactly the same as in the octave 10kHz to 20kHz.
		This converts the white noise into pink noise, having equal energy in all 10 octaves of the audio band.

		The amplifier must have low noise current since a farily high value resistor is used to generate the 50 nV white noise; choose an op-amp with noise voltage less than 15 nV/root-Hz and noise current less than 0.1 pA/root-Hz, both easily obtained with several modern op-amps.
