Transient Otoacoustic Emissions (TEOAE) Otoacoustic emissions (OAE) are low intensity sounds generated by the outer hair cells (OHC) of the inner ear. When we speak about otoacoustics emissions, we primarily think about transient otoacoustic emissions also called TEOAE which are most used in clinical examination. OAE are recorded by a small probe place in the external ear canal. Detection of transient otoacoustic emissions (TEOAE) is a real asset in the series of hearing tests. User Tips: Make sure that ear canal is not obstructed by earwax. Choice of eartip is the most important point for the quality of the measurement. Eartip should not be pressed against a side of the ear canal. Eartip must be sealed to prevent acoustic leaks and isolate to surrounding noise. Measure specifications: Per click Sound intensity: 84dB HL Aimed diseases: objective diagnosis of hearing loss, monitoring of cochlear damage. Method: The TEOAE are otoacoustic emissions by click, which means that we are going to test patient ear with frequencies between 2000 and 4000 Hz. The result is represented by a curve that simply shows whether otoacoustic emission is present or not. This is an objective test because he does required cooperation of the patient. This test is very important, in especially in the examination of newborns, because if the acoustic otoemissions are present it means that hearing of newborn does not present deafness superior to 30-40 dB. It is a screening test routine, more and more used in examination of newborns.
