MSU Graduate Theses
Distortion-product otoacoustic emissions (DPOAEs) are objective tests of the integrity of the outer hair cells of the cochlea in response to a single-tone pair stimulus. Despite advances in DPOAEs test protocols and technology, there is little research about the use of frequency modulated tones to improve response characteristics. This study evaluates the efficacy of a new frequency modulated stimulus with multiple-tone pair DPOAEs (mDPOAEs) compared to the standard stimulus protocol for mDPOAEs to determine whether frequency modulation (FM) will achieve more robust and faster results. Normative data for this novel test protocol were obtained in 11 healthy normal-hearing children aged …
