4/3/2023 0 Comments Types of tympanogramsIn evaluating hearing loss, tympanometry permits a distinction between sensorineural and conductive hearing loss, when evaluation is not apparent via Weber and Rinne testing. Tympanometry is a valuable component of the audiometric evaluation. The test should not be used to assess the sensitivity of hearing and the results of this test should always be viewed in conjunction with pure tone audiometry. It is an acoustic measure, measured by a microphone, as part of the ear canal probe, inserted into the ear canal. It is not a measure of TM or middle ear mobility. It is not a hearing test, but rather a measure of energy transmission through the middle ear. Tympanometry is an objective test of middle-ear function. Tympanometry is an acoustic evaluation of the condition of the middle ear eardrum ( tympanic membrane) and the conduction bones by creating variations of air pressure in the ear canal.
