Activating the medial olivocochlear system reduces the asymmetry of SOAE bouncing

Evidence

Overall, temporary level reductions of preexisting SOAEs were less pronounced with CAS than without (Wilcoxon signed rank test, p = 0.085 and 0.007 for CAS levels of 65 and 70 dB, respectively), while the SOAE level increases remained fairly unchanged. This resulted in a less symmetrical shape of the SOAE Bounce compared to the reference recording. Consequently, the time constants of the fitted function with CAS shortened significantly. — Dijk, Pim van, Physiology, Psychoacoustics and…, 3743
