Frequently Asked Questions
- A probe with a soft plastic tip is inserted in the ear canal until an airtight seal is obtained.
- Later, probe tone (typically 226 Hz) is stimulated into the ear canal while altering air pressure of the external ear canal from +200 to -400 decapascal (daPa).
- Result is produced in a form of graph marking admittance as a function of air pressure.
- No major preparation is required.
- For patients who have undergone ear surgery, Impedance is not advisable.
- Low-frequency tympanometry is not recommended for infants younger than 7 month.
For an effective Impedance audiometry session it fetches around 15 – 20mins for completion. Clinical reports will be provided immediately after test.
