This study characterized medial olivocochlear (MOC) reflex activity on synchronized spontaneous otoacoustic emissions (SSOAEs) as compared to transient-evoked otoacoustic emissions (TEOAEs) in normal-hearing adults. Using two time windows, changes in TEOAE and SSOAE magnitude and phase due to a MOC reflex elicitor were quantified from 1 to 4 kHz. In lower frequency bands, changes in TEOAE and SSOAE magnitude were significantly correlated and were significantly larger for SSOAEs. Changes in TEOAE and SSOAE phase were not significantly different, nor were they significantly correlated. The larger effects on SSOAE magnitude may improve the sensitivity for detecting the MOC reflex.
