An otoacoustic emission system, line-powered, is a medical device assembly that uses mains electricity to generate sound stimuli and measure the faint acoustic responses from the inner ear. It is used clinically to assess cochlear function, particularly in diagnostic hearing evaluations and newborn hearing screening programs, by detecting whether hair cells in the ear are functioning properly.
Devices in this category are regulated as medical devices that require electrical safety compliance due to their line-powered design. They are typically supplied as integrated systems including a stimulus generator, probe with microphone, and disposable eartips, and may be used alongside other audiometric equipment such as tympanometers or auditory brainstem response devices.
