Grey noise is random noise whose frequency spectrum follows an equal-loudness contour (such as an inverted A-weighting curve).. Grey noise spectrum. The result is that grey noise contains all frequencies with equal loudness, as opposed to white noise, which contains all frequencies with equal energy.
