OHC dysfunction is associated with threshold shifts due the lack of active amplification of the vibrations on the basilar membrane (BM). This active mechanism is also responsible for the compressive BM input/output function characterizing the normal system. The supra-threshold deficits associated with OHC dysfunction are, e.g.,
