Hearing loss often gets undetected for long amongst many individuals. Thus it remains untreated. The reasons for this may be many. It may range from lack of identifying the symptoms to saving oneself from the embarrassment one feels from the problem. Whatever it is, determining the type and cause of your hearing loss is essential in its treatment. This could only be done through various hearing evaluation tests. Early detection of hearing losses may be critical to save one from further damage. So these hearing tests are essential in determining the right treatment and recovery. One of the hearing tests often used by audiologists is Tympanometry. Let us first try to understand the process.
Tympanometry: what it is?
Tympanometry is a test which is used to evaluate the proper functioning of your middle ear. It can determine whether your hearing loss can be helped by hearing aids or whether a medical treatment is available to treat your loss instead. It assesses the condition of the middle ear and the mobility of the ear drum. This is called the “Tympanic Membrane”. It also is used to evaluate the conduction of the bones in the middle ear. The results from this test are represented on a graph which is known as a Tympanogram.
How the test is performed?
This test is carried out at the clinic. The Audiologist would generally first inspect your ear canal and ear drum visually. He or she would do this using a lighted scope also called an otoscope by placing it in your ear. Then they would place a probe with a flexible rubber tip in your ear. They would apply air pressure in your ear canal using this. They would change the applied air pressure and you might be able to hear some low pitched tones. The feeling inside your ear will be similar to what you feel when you are travel in an aero plane while it is taking off and landing. Measurements of your eardrum would be taken with the changing air pressure in your ear are recorded.
Audiologists carry out this test to evaluate the energy transmission levels in the middle ear. They do this test to distinguish between sensorineural and conductive hearing loss. This test could be carried out in any person irrespective of age. There is no major risk involved. But there is a possibility that you may feel a bit uncomfortable during the process. This is because you may be hearing loud tones during the tests. You may not be allowed to speak or swallow when the procedure is being carried out. This is because wrong readings may be recorded otherwise. Thus in case you have children on whom this test is to be carried, you need to divert their attention. However one advantage is that the tests requires little time.
Normal results from the test may be absence of any fluid and normal pressure in the middle ear, normal movements of the eardrum and conducting bones. However in case if you have fluid in the middle ear then the ear pressure may higher than the normal range. Once detected the audiologist uses the results for determining the course of the hearing loss treatment.
