Normal tympanometry results. A normal tympanogram (called "type A") shows that your eardrum moves easily in response to changes in air pressure. It resembles a mountain or teepee.
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 ...
In addition, a test called a tympanogram is generally done. In this test, a small probe is placed in the ear and the air pressure in the ear canal is varied. This test tells the audiologist how well the eardrum and other structures in the middle ear are working. The ear canal volume indicates whether a perforation in the eardrum (tympanic ...
Acoustic immittance audiometry - Immittance audiometry is an objective technique which evaluates middle ear function by three procedures: static immittance, tympanometry, and the measurement of acoustic reflex threshold sensitivity. Immittance audiometry is superior to pure tone audiometry in detecting middle ear pathology. Tympanometry
The results of pure-tone audiometry are however a very good indicator of hearing impairment. Hearing disability is defined by the WHO as a reduction in the ability to hear sounds in both quiet and noisy environments (compared to people with normal hearing), which is caused by a hearing impairment.

For cases of baro-challenge induced Eustachian tube dysfunction, diagnosis usually relies on the history of the patient and their reported symptoms, as otoscopy and tympanometry is sometimes normal at normal ambient pressure. [1]
tympanometry differential testing – the Weber , Rinne , Bing and Schwabach tests are simple manual tests of auditory function conducted with a low frequency (usually 512 Hz) tuning fork that can provide a quick indication of type of hearing loss: unilateral/bilateral, conductive, or other
“And I was just like, ‘Okay.’ That's, like, what's actually out in the world because of people creating hate,” she continued. “I'm a mom.
