A hearing test that measures the ability of the tympanic membrane in the ear to move in response to air pressure (rather than sound).
A test done to determine whether allergy or infection is interfering with adequate functioning of the eardrum. Varying tones are administered to the outer ear canal, and the pressure response within the ear is recorded on a graph.
A test of the movement of the eardrum (tympanic membrane) to determine if there is fluid in the middle ear space and to measure the air pressure if there is no fluid. Tympanometry is not a hearing test and cannot measure a person’s ability to hear: Rather, it is a diagnostic tool used to determine a possible cause of hearing loss or impairment.
A procedure for objective evaluation of the mobility and patency of the eardrum and for detection of middle-ear disorders and patency of the eustachian tubes.
This hearing assessment method is employed to determine the underlying reason behind conductive deafness. In this procedure, a device consisting of a tone generator, a microphone, and an air pump is inserted into the outer ear canal. By altering the air pressure within the ear and emitting tones into it, the reflected tone pattern from the eardrum is captured by the microphone. This pattern provides insight into the eardrum’s regular motion and functionality.
Tympanometry proves especially valuable when examining children, as it doesn’t depend on receiving a response from the individual undergoing the test.
