[[Grey noise]] is random white noise subjected to a [[Psychoacoustics|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.{{Citation needed|date=March 2010}} This is in contrast to standard white noise which has equal strength over a linear scale of frequencies but is not perceived as being equally loud due to biases in the human [[equal-loudness contour]].
