Contralateral efferent inhibition is proportional to output energy, magnifying inter-aural differences.

Evidence

This is because the gain (or compression) in the each of the two MOC processors was inhibited in direct proportion to the output energy from the corresponding frequency channel in the contralateral processor. Because the stimulus level was higher on the left ear, the output amplitude was also higher for the leftthan for the right-ear MOC processor. Hence, the left-ear MOC processor inhibited the right-ear MOC processor more than the other way around. — Dijk, Pim van, Physiology, Psychoacoustics and…, 1961
