Tympanometers are devices for testing hearing that measure changes in acoustic impedance or admittance by varying air pressure in the external acoustic meatus or activating the middle ear muscle reflex. These devices are intended to detect possible otologic disorders associated with middle ear functioning and are used in hospitals, clinics, or other healthcare facilities with suitable quiet testing environments.
