A hearing screening consists of a quick (10-15 minute) screening of the ability to hear at select frequencies at one intensity level in each ear. The audiologist may also take measurements that will provide information about the status of the outer and middle ear. These are called acoustic immittance measures. Tympanometry, one aspect of immittance testing, can assist in the detection of fluid in the middle ear, perforation of the eardrum, or wax blocking the ear canal. Acoustic reflex measurement, another aspect of immittance testing, can add diagnostic information about middle ear function and hearing loss.
The audiologist will use an otoscope, an instrument that contains a light and a magnifying lens, to examine the ear canal and eardrum.
Anyone who has any indicators of hearing problems will be referred for further evaluation.
