Loud masking sounds asymmetrically mask higher frequencies more than lower ones

Evidence

At low amplitude levels, the masking effect tends to be similar for frequencies above and below fmasker. As the amplitude of the masker is raised, the low masks high effect increases and the resulting masking level curve becomes increasingly asymmetric. Thus the masking effect is highly dependent on the amplitude of the masker. — David Howard, Jamie Angus, coustics and Psychoacoustics, 1638
