Cochlear compression shows hysteresis with faster attack than decay at high modulation rates.

Evidence

The observed decreases in envelope gain and in gain peakedness with increasing beat rate act synergistically to reduce the amount of compression exhibited in the BM response envelopes at high beat rates. This “linearization” is illustrated directly in Fig. 3 by plotting the response envelopes as a function of the instantaneous intensity of the beating stimulus. … One consequence of this linearization is that BM’s response dynamics can actually enhance the encoding of dynamic stimuli, within certain limits. However, this “enhancement” comes at the price of reduced overall sensitivity. — Dijk, Pim van, Physiology, Psychoacoustics and…, 3637 (#expands, via linked claim)
