[Short-term reproducibility of acoustic oto-emissions induced by clicks in adults].
Otoacoustic emissions (OAE) are sounds emitted by the cochlea and recordable in the external ear canal by a miniature microphone. The OAE reflect the existence of an active mechanism within the cochlea. Development of the OAE has spurred much interest because they may used as a valid test for screening and monitoring cochlear changes. The OAE were recorded in 8 normal hearing subjects (15 ears) during nine test sessions under similar conditions. The aim of this work was to study the short-term variability in the amplitude of the emissions. Results of the study indicate that response levels are stable over time in the same ear therefore changes in the response level can be associated with changes in the cochlea.
