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 white noise, noise which is in fact equally loud at all frequencies but not perceived as such due to psychoacoustics.
