Shahnaz and colleagues also noted that, for newborns who passed ABR and OAE screenings, the 1000 Hz tympanograms were bell-shaped, had single peaks, and were well defined (with very few exceptions).

Tympanometry as a test of otologic status has the following attributes, uses, and advantages: (1) can be carried out simply, rapidly, and atraumatically, by appropriately trained nonprofessionals; (2) does not require, as does conventional audiometry, a sound-free environment; (3) is not influenced by the amount of cerumen ordinarily present in the external auditory canal; (4) is entirely

Tympanometry helps to find and diagnose disorders that may lead to or have already caused a hearing loss. Tympanometry, Impedance, Otosclerosis, Tympanogram,OME, Jerger Tympanogram Classification, Type A, As, Ad, B, C A “Type B” curve has no sharp peak and little or no variation in impedance over a wide sweep range. This is indicative of non-compressible fluid within the middle ear space (otitis media), tympanic membrane perforation, or debris within the external ear canal (cerumen). With the third pattern, a “Type … Tympanometry is a type of test that measures the function of the middle ear.
