Tympanometry is a test that is used to assess your middle ear function. It is quick, painless, and noninvasive. This test is often used to diagnose problems with the eardrum or middle ear such as ...
Tympanometry is an acoustic evaluation of the condition of the middle ear [1] eardrum (tympanic membrane) and the conduction bones by creating variations of air pressure in the ear canal. Tympanometry 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. It is ...
Tympanometry, or acoustic immitance testing, is a simple objective test of the ability of the middle ear to transmit sound waves from the outer ear to the middle ear and to the inner ear. This test is usually abnormal with conductive hearing loss.
Eustachian tube dysfunction (ETD) is a disorder where pressure abnormalities in the middle ear result in symptoms. [2] ... usually a tympanometry is indicated, ...

The severity of a hearing loss is ranked according to ranges of nominal thresholds in which a sound must be so it can be detected by an individual. It is measured in decibels of hearing loss, or dB HL. The measurement of hearing loss in an individual is conducted over several frequencies, mostly 500 Hz, 1000 Hz, 2000 Hz and 4000 Hz. The hearing ...
Hereditary ataxias, such as Friedreich’s ataxia, are genetic, meaning they are caused by "a defect in a certain gene that is present from the start of a person’s life, inherited from your ...
The result is a tympanogram showing ear canal volume, middle ear pressure and eardrum compliance. Normal middle ear function (Type A tympanogram) with a hearing loss may suggest presbycusis. Type B and Type C tympanograms indicate an abnormality inside the ear and therefore may have an additional effect on the hearing.
