Evoked OAEs, or evoked otoacoustic emissions, 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, a part of the inner ear, and can be measured using a sensitive microphone placed in the ear canal. They provide valuable information about the functioning of the auditory system. These emissions are commonly used in hearing tests, especially for newborns and young children, to screen for hearing loss. The presence of evoked OAEs indicates normal cochlear function, while their absence may suggest hearing impairment or damage to the inner ear structures.
