An Otoacoustic Emission (OAE) Machine is a diagnostic tool used to evaluate hearing health by measuring otoacoustic emissions, sounds generated by the inner ear (cochlea) in response to an auditory stimulus. This non-invasive device plays tones or clicks through a small probe inserted into the ear canal and records the ear’s response. OAE machines are essential in newborn hearing screening, as they quickly detect cochlear health and identify potential hearing loss. They’re also used in regular hearing assessments for children and adults. The machine’s portability and quick test results make it efficient for early diagnosis and intervention. With high accuracy, it helps audiologists determine if hearing loss is present, providing valuable information for further evaluation and treatment planning.
