Equal-loudness contour — An equal loudness contour is a measure of sound pressure (dB SPL), over the frequency spectrum, for which a listener perceives a constant loudness when presented with pure steady tones. The unit of measurement for loudness levels is the phon, and … Wikipedia
Loudness — is the quality of a sound that is the primary psychological correlate of physical strength (amplitude).Loudness, a subjective measure, is often confused with objective measures of sound pressure such as decibels or sound intensity. Filters such… … Wikipedia

Colors of noise — White Pink Red (Brownian) Grey While noise is by definition derived from a random signal, it can have different characteristic statistical properties corresponding to different mappings from a source of randomness to the concrete noise. Spectral… … Wikipedia
Grey noise — is random noise subjected to a psychoacoustic equal loudness curve (such as an inverted A weighting curve) over a given range of frequencies, giving the listener the perception that it is equally loud at all frequencies. This is in contrast to… … Wikipedia
