Transient evoked otoacoustic emissions (TEOAEs) are not necessarily recordable in all healthy neonates, before discharge, due to transient conditions (such as vernix in ear canals). To determine the possibility and feasibility of screening of very young newborns before discharge from hospital (JCIH, 2007), it is important to know how vernix in external ear during this time affects screening res...

Click-evoked otoacoustic emission (CEOAE) input/output (I/O) functions were measured in ears with normal hearing and in ears with sensorineural hearing loss above 2000 Hz. The low- to midfrequency CEOAEs obtained from the ears with high-frequency hearing loss were significantly reduced in level compared to the CEOAEs obtained from the ears with normal hearing even though there were no significa...

Otoacoustic Emissions (OAEs) are sounds which emerge from ear canal when (paradoxically) tympanic membrane receives vibrations from cochlea transmitted by middle ear. The present study was taken up as the literature review shows that the effect of different click durations on the presence of Transient Evoked Otoacoustic Emission (TEOAE) has not been studied. The present study involved 15 subjec...

healthy newborns due to its lower false-positive and referral rates, high specificity, and also its’ ability to diagnose auditory neuropathy spectrum disorder combination with Transient Evoked Otoacoustic Emissions test. On the other hand, the test time can be a disadvantage. With technological advancements, a new generation Automated Auditory Brainstem Response has been developed which is fast...
