GMDN Terms

Code	Name	Definition	Implantable	Status
36717	Impedance audiometer	An electronic instrument used to evaluate the functional condition of the middle ear by changing the air pressure in the external auditory canal to measure and graph the mobility characteristics of the tympanic membrane. It identifies abnormalities in tympanic membrane mobility due to stiffness, flaccidity, or the presence of fluid in the middle ear cavity. The device is also used to measure the acoustic reflex threshold from contractions of the stapedial muscle, to monitor healing of tympanic membrane grafts or stapedectomies, or to monitor follow up treatment for inflammation of the middle ear.	No	Active
37503	Tone audiometer	An electroacoustic device intended for use in a clinical setting to generate tones in the audible range to measure the hearing threshold of a patient by establishing the level at which the patient first becomes aware of the sounds. The device controls tone intensity and frequency either by a computer or manually, and displays/records the patient's responses, typically in the form of an audiogram. It may include a bone vibrator for direct inner-ear stimulation.	No	Active
41188	Speech audiometer	An electroacoustic device designed to measure the hearing threshold of a patient by presenting words of increasing or decreasing intensity through headphones, which the patient is required to recognize and repeat, to establish the hearing capacity of the patient and to determine if a hearing deficit exists.	No	Active
58019	Otoacoustic emission system, battery-powered	An assembly of battery-powered devices designed to record and analyse the faint sounds hair cells in the inner ear emit [otoacoustic emission (OAE)] in response to a stimulus (e.g., click, tone burst, pure-tone signals) to test for a deficiency of function in the ear during diagnostic evaluation and/or neonatal screening. It typically consists of a portable programmable unit, an OAE probe, and eartips. The stimulus signal is emitted via the probe inserted into the ear canal and the response is recorded via a microphone in the probe; OAEs are absent/reduced in patients with hearing loss. The system may be combined with other audiological devices (e.g., tympanometer, ABR device).	No	Active
