Otoacoustic-emission-based medial-olivocochlear reflex assays for humans.
Otoacoustic emission (OAE) tests of the medial-olivocochlear reflex (MOCR) in humans were assessed for viability as clinical assays. Two reflection-source OAEs [TEOAEs: transient-evoked otoacoustic emissions evoked by a 47 dB sound pressure level (SPL) chirp; and discrete-tone SFOAEs: stimulus-frequency otoacoustic emissions evoked by 40 dB SPL tones, and assessed with a 60 dB SPL suppressor] w...

متن کاملFrequency tuning of the contralateral medial olivocochlear reflex in humans.
Activation of the medial olivocochlear (MOC) efferents attenuates cochlear gain and reduces the amplitudes of mechanical, electrical, and neural cochlear outputs. The functional roles of the MOC efferents are not fully understood, especially in humans, despite postulations that they are involved in protection against acoustic trauma, facilitation of transient-sound perception, etc. Delineating ...
متن کاملStudy of the medial olivocochlear efferent system through otoacoustic emissions
The purpose of this study was to investigate the efferent medial olivocochlear system through the use of otoacoustic emissions and especially the modifications that occur at this level with age. The activity of outer hair cells (OHCs) (peripheral) and of the efferent medial olivocochlear (MOC) system (neural and central) was examined by means of distortion product otoacoustic emissions (DPOAEs)...
متن کاملEfferent Modulation of Stimulus Frequency Otoacoustic Emission Fine Structure
Otoacoustic emissions, sounds generated in the inner ear, have become a convenient non-invasive tool to examine the efferent modulation of cochlear mechanics. Activation of the medial olivocochlear (MOC) efferents has been shown to alter the magnitude of these emissions. When the effects of efferent activation on the detailed spectral structures of these emissions have been examined, a shift of...
