A.T. Still University-Arizona School of Health Sciences (ATSU-ASHS) second-year students of audiology practiced immittance audiometry testing during a recent clinical module.
“Immittance audiometry is a physiologic measure, the primary purpose of which is to determine the status of the tympanic membrane (eardrum) and middle ear via tympanometry, a graphic representation of middle ear function,” said Zarin Mehta, PhD, CCC-A, FAAA, associate professor, audiology. “The secondary purpose of this test is to evaluate acoustic reflex pathways, which include cranial nerves VII and VIII and the auditory brainstem.”
“Recently, wideband tympanometry has become clinically available. It assesses middle ear function with multiple frequencies at the same time represented by a 3D image,” Dr. Mehta said. “This technology has the ability to detect a number of middle ear disorders that were missed by traditional tympanometry.”
