What is an Impedance Audiometry Test?
Impedance Audiometry, also known as Tympanometry, is a hearing test that checks how well the eardrum (tympanic membrane) moves in response to changes in air pressure. Unlike Pure Tone Audiometry, which tests how well you hear different sounds, Impedance Audiometry evaluates the health and function of the middle ear — including the eardrum, the tiny middle ear bones (ossicles), and the Eustachian tube.
The test does not require any active response from the patient and takes only a few minutes to complete, making it especially useful for testing young children and individuals who cannot reliably respond to sound-based tests.
At Modern Hearing Care Clinic, Impedance Audiometry includes Acoustic Reflex testing as part of the standard protocol, alongside Tympanometry.
Why is Impedance Audiometry Important?
An Impedance Audiometry test helps to:
- Detect fluid buildup in the middle ear (common in ear infections)
- Identify a perforated or damaged eardrum
- Check for Eustachian tube dysfunction
- Detect stiffness or reduced movement of the middle ear bones
- Support diagnosis of conditions such as otitis media (middle ear infection)
This test is often recommended by ENT doctors as part of a complete ear evaluation.
Who Should Get an Impedance Audiometry Test?
You may need this test if you experience:
- Ear pain or a feeling of fullness in the ear
- Frequent ear infections
- A recent cold or upper respiratory infection affecting your hearing
- Fluid drainage from the ear
- Sudden or fluctuating hearing loss
- As part of a complete hearing evaluation alongside PTA and OAE
The Impedance Audiometry Testing Process at Modern Hearing Care Clinic
- Consultation — A brief discussion about your hearing concerns and medical history
- Testing — A small soft probe is placed at the entrance of your ear canal, and air pressure is varied while your eardrum’s response is measured
- Report — Results are recorded on a tympanogram and explained by Dr. Mallala Kirankumar, MASLP
- Consultation on Results — Findings are discussed, along with any recommended next steps
The entire process typically takes around 10 minutes.
