Effective attenuations induced by the medial olivocochlear (MOC) efferent reflex elicited with broadband noise contralateral acoustic stimulation. Effective attenuations of compound action potentials (CAPs) were calculated using average CAP-vs-sound-level growth (X’s) or from individual CAP-vs-sound-level growth (circles). CAP bars are 95% confidence intervals estimated by a bootstrap using the CAP null distribution and the distribution of the CAP growth functions (see Methods). Effective attenuations of distortion product otoacoustic emissions (DPOAEs) are shown as triangles with bootstrapped 95% confidence intervals (see Methods).
