Tympanometry / Impedance Hearing Test
Tympanometry / Impedance Hearing Test
Tympanometry/Impedance Hearing Test is a type of hearing test that measures the movement of the eardrum in response to changes in air pressure, while impedance audiometry is a broader category of tests that includes tympanometry and other measures of the middle ear. Here are some important facilities of Tympanometry/Impedance Hearing Test:
Objective measurement.
Non-invasive.
Quick and easy.
Tympanometry is a quick and easy test that typically takes only a few minutes to complete.
Provides information on the middle ear.
Tympanometry provides information on the movement and compliance of the middle ear, which can help diagnose conditions such as otitis media, tympanic membrane perforation, and Eustachian tube dysfunction.
Helps identify hearing loss.
Tympanometry can help identify conductive hearing loss, which occurs when sound is not transmitted properly through the middle ear.
Can be used in infants and young children.
Tympanometry / Impedance Hearing Test
First of all
The patient sits comfortably in a chair or lies down on an exam table, while the healthcare professional inserts a small probe into the ear canal.
Second
The probe generates a sound and changes the air pressure in the ear canal, while a microphone in the probe measures the sound waves that bounce back from the eardrum.
Three
The equipment then calculates the amount of sound that was absorbed by the eardrum and the amount that was reflected back, and creates a graph called a tympanogram that displays the results.
Fourth
The tympanogram displays information about the movement and compliance of the eardrum in response to changes in air pressure, and can help diagnose a variety of middle ear conditions such as fluid buildup, perforated eardrum, or Eustachian tube dysfunction.
Five
The test may take only a few minutes to complete, and is generally well-tolerated by patients of all ages. It is important to follow the healthcare professional's instructions during the test to ensure accurate results.
Six
Overall, Tympanometry/Impedance hearing test is a valuable tool for diagnosing and monitoring a variety of middle ear conditions, and is a safe and non-invasive procedure that can be performed quickly and easily by a trained healthcare professional.

Frequently Asked Questions
During a tympanometry/impedance test, you can expect the following:
Preparation: Before the test, the audiologist or hearing healthcare professional will examine your ears to ensure that they are clear of wax and debris. They will also ask you about any symptoms you may be experiencing, such as ear pain or hearing loss.
Placement of probe: A small probe will be placed in your ear canal. The probe will create a seal in your ear canal and change the air pressure in your ear. You may feel some pressure or discomfort, but it should not be painful.
Tones and sounds: During the test, you will hear different tones and sounds in your ear. The audiologist or hearing healthcare professional will measure how your ear responds to these sounds.
Results: Based on the measurements taken during the test, the audiologist or hearing healthcare professional will be able to determine if there are any issues with your middle ear, such as fluid build-up, eardrum perforation, or problems with the small bones in your ear.
Duration: The test usually takes about 5 to 10 minutes to complete.
Overall, the tympanometry/impedance test is a non-invasive and painless way to assess the health of your middle ear and determine if any hearing issues are present.
