The MOCR reduces channel compression when the opposite ear’s output rises

Evidence

The extent to which a compressive input-output relation holds when the intensity of a stimulus fluctuates in time has not been studied systematically, however, and the possibility that the cochlea operates more like an automatic gain control (AGC) system than an instantaneously nonlinear system remains feasible (van der Heijden 2005 ). — Dijk, Pim van, Physiology, Psychoacoustics and…, 3628 (#expands, via linked claim)
