Cochlear compression shows asymmetric envelope at high beat rates.

Evidence

At low beat rates (e.g., for Δf = f2 ‑f1 ~ 10–160 Hz), observed response envelopes appeared symmetric in the time domain (cf. Fig. 1 c ). At higher rates, however, the rising flanks of the response envelopes became steeper than the falling flanks (cf. Fig. 1 a , b ). This temporal asymmetry reflects hysteresis, and is reminiscent of the output of a gain control system with separate attack and decay time-constants. — Dijk, Pim van, Physiology, Psychoacoustics and…, 3637
