In the transient-evoked otoacoustic emission TEOAE-based medial-olivocochlear reflex MOCR assay developed by Marshall et al. 2014, a higher TEOAE stimulus level could improve TEOAE signal-to-noise ratio and MOCR measurability. However, a higher level may evoke a confounding ipsilateral MOCR in addition to the contralateral MOCR from the broadband noise elicitor. This study was designed to establish if the TEOAE chirp stimulus could evoke a MOCR by using it as the contralateral MOCR elicitor in place of the broadband noise. A stimulus-frequency otoacoustic emission SFOAE-based MOCR assay was used because tonal SFOAE stimuli do not elicit a confounding MOCR at the levels used.
