evoked otoacoustic emissions
Evoked otoacoustic emissions (EOAEs) are sounds produced by the inner ear in response to auditory stimuli, such as clicks or tones. These emissions are generated by the outer hair cells of the cochlea, which amplify sound vibrations. EOAEs are used to assess hearing function, particularly in newborns and individuals who may not be able to communicate their hearing ability.
The presence of EOAEs indicates that the cochlea is functioning properly, while their absence may suggest hearing loss or damage to the inner ear. This non-invasive test is valuable for early detection of hearing issues, allowing for timely intervention and support.
