In combination with a comprehensive hearing test, tympanometry can confirm whether the middle ear is the source of your hearing difficulty. Normal tympanometry results
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 ...
The result of the test is an audiogram diagram which plots a person's hearing sensitivity at the tested frequencies. On an audiogram an "x" plot represents the softest threshold heard at each specific frequency in the left ear, and an "o" plot represents the softest threshold heard at each specific frequency in the right ear.
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.

The tone decay test (also known as the threshold tone decay test or TTDT) is used in audiology to detect and measure auditory fatigue. It was developed by Raymond Carhart in 1957. In people with normal hearing, a tone whose intensity is only slightly above their absolute threshold of hearing can be heard continuously for 60 seconds.
A tympanogram is the result of a test with a tympanometer. It tests the function of the middle ear and mobility of the eardrum. It tests the function of the middle ear and mobility of the eardrum. It can help identify conductive hearing loss due to disease of the middle ear or eardrum from other kinds of hearing loss including SNHL.
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.
