Tympanometry
Tympanometry is a quick test that gives us important information about how your middle ear is functioning. If hearing seems off, pressure feels unusual, or results from other tests do not fully line up, tympanometry helps us understand what is happening behind the eardrum.
At Northwest Hearing + Tinnitus, tympanometry is typically part of a broader diagnostic evaluation. It helps our audiologists determine whether a concern is coming from the middle ear or the inner ear, which is a key distinction for choosing the right next step.

What is Tympanometry?
Tympanometry is a simple, non-invasive test that evaluates how well your eardrum and middle ear are working. Instead of measuring what you hear, it measures how your ear responds to slight changes in air pressure.
During the test, a small probe is placed in the ear canal. The device briefly changes air pressure and measures how the eardrum moves in response. This gives your audiologist valuable information about:
- Middle ear pressure
- Eardrum mobility
- The condition of the middle ear space
The test takes only a few seconds and provides immediate results.
What Tympanometry Helps Identify
Tympanometry does not diagnose conditions on its own, but it helps identify patterns that guide clinical decision-making.
It is commonly used to detect signs consistent with:
- Middle ear fluid
- Eustachian tube dysfunction
- Abnormal middle ear pressure
- Reduced eardrum mobility
It can also help flag findings that may suggest:
- Eardrum perforation
- Ossicular chain issues (problems with the tiny bones in the middle ear)
- Situations where hearing test results do not fully match expected patterns
If results suggest a possible medical issue, your audiologist may recommend a referral to an ENT for further evaluation.
What Tympanometry Doesn’t Do
Tympanometry is often misunderstood.
It does not measure hearing ability or determine how well you hear different sounds.
It does not diagnose sensorineural hearing loss.
Instead, it is a supporting test that helps explain why hearing may be affected. It works alongside other tests to give a more complete picture of your hearing and ear health.
What to Expect During Tympanometry
Tympanometry is quick and straightforward.
Here is what happens:
- A small probe is placed gently in your ear
- You may feel a slight change in pressure, similar to going up or down in elevation
- The device measures how your eardrum responds
- The test is complete in just a few seconds per ear
There is no pain, and most patients tolerate it very well.
For many people, it is one of the fastest parts of a hearing evaluation.

When Tympanometry is Used
Tympanometry is rarely performed as a standalone appointment.
It is typically used when your audiologist needs more information about how your ear is functioning.
You may have tympanometry as part of an evaluation if you are experiencing:
- A feeling of fullness or pressure in the ear
- Sudden or fluctuating hearing changes
- Difficulty that does not match typical hearing loss patterns
- A history of ear infections or middle ear issues
It is also used to cross-check findings from other hearing tests to ensure results are accurate and complete.
Why the Middle Ear vs Inner Ear Matters
Not all hearing problems come from the same place.
Some issues involve the inner ear, which affects how sound is processed. Others involve the middle ear, which affects how sound is transmitted. Tympanometry helps us distinguish between the two.
That distinction matters because it changes the next step. If the issue appears to involve the middle ear, medical evaluation by an ENT may be needed. If the issue is related to the inner ear, hearing-focused treatment may be the right path.
Getting this right early prevents wasted time and leads to better outcomes.
