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 ...
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. Abnormal tympanometry results

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 ...
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]
Other method for quantifying hearing loss is a hearing test using a mobile application or hearing aid application, which includes a hearing test. [1] [2] Hearing diagnosis using mobile application is similar to the audiometry procedure. As a result of hearing test, hearing thresholds at different frequencies are determined.
