Witryna18 mar 2013 · The purpose of this study was to quantify the change in distortion product otoacoustic emission (DPOAE) level upon ear canal pressurization. DPOAEs were measured on 12 normal-hearing human subjects for ear canal static pressures between −200 and +200 daPa in (50 ± 5) daPa steps. A clear dependence of DPOAE levels …

Witryna31 mar 2016 · Given that the medial olivocochlear efferent system reduces the amplitude of otoacoustic emissions (OAE), the aim of this study was to establish whether such a pathway is affected in women with migraine and phonophobia by means of OAE suppression testing. In this prospective case–control study, 55 women (29 with … Witryna30 sty 2007 · The clinical use of OAEs promises to change as more understanding is gained about their generation processes (see refs. 9and 10for recent reviews). At the moment, the most widely studied OAE is the cubic distortion product (DP) of the OAE (DPOAE), which is generated when stimulating with two tones (of frequency f1and f2). Witryna1 lip 2013 · OAEs are used to assess cochlear integrity and are physiologic measurements of the response of the outer hair cells to acoustic stimuli. They serve as a fast objective screening test for normal preneural cochlear function through the use of probe in the ear canal. 19, 20 tsunamis may be caused by
