The origin of impedance audiometry. Thomsen KA. Impedance audiometry is performed every day in nearly every ENT department, office and, audiology clinic all over the world. But hardly anyone occupied with these measurements has any idea of the origin of this Danish contribution to otolaryngology. PMID: 10320068 [PubMed - indexed for MEDLINE]

This manuscript has attempted to briefly outline the most important areas of clinical impedance audiometry. The author has emphasized the use of impedance audiometry in differentiating different types of middle ear pathology and utilizing the stapedial reflex in the determination of malingering as well as an overall test of the normal function of the auditory nervous system …

For impedance audiometry, a hermetic seal is obtained by inserting a probe tip in the external ear canal. The pressure in the enclosed cavity is varied from + 200 to − 200 mm H 2 O and the change in sound pressure level of a probe tone is graphed. This shows the movement of the middle ear system as pressure is varied.

In human ear: Audiometry …and brainstem is supplied by impedance audiometry. Two small tubes are sealed into the external canal. Through one tube sound from a small loudspeaker is injected into the canal. The portion that is reflected from the tympanic membrane is picked up by the other tube and led to a microphone,… Read More

The main purpose of impedance audiometry is to check the status of the tympanic membrane and middle ear. The main purpose of impedance audiometry is to check the status of the tympanic membrane and middle ear. It checks how well the vibrations get transmitted from the tympanic membrane (eardrum) further into the ear.
