<unk>  is an examination used to test the condition of the middle ear and mobility of the eardrum (tympanic membrane) and the conduction bones, by creating variations of air pressure in the ear canal.<unk>  is an objective test of middle-ear function. It is not a hearing test, but rather, a measure of energy transmission through the middle ear. This 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.<unk>  is a valuable component of the audiometric evaluation. In the evaluation of hearing loss,<unk>  is a valuable component of the distinction between sensorinueural and conductive hearing loss, when evaluation is not apparent via Weber and Rinne testing.
