Otoacoustic Emission (OAE) Based Assays of the Medial Olivocochlear Reflex (MOCR): Ensuring the OAE Stimulus Does Not Cause a Confounding MOCR

Abstract

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.
