Otoacoustic Emissions (OAE) testing is a quick, non-invasive procedure that evaluates the function of the inner ear. It measures sound waves produced by the hair cells in the cochlea in response to auditory stimuli, helping to detect hearing loss or other inner ear issues. OAE testing is particularly valuable for newborns, young children, and individuals who may not be able to respond to conventional hearing tests, providing essential insights for diagnosis and treatment.
