Impedance audiometry is done using frequency probe of
**Core Concept**
Impedance audiometry is a diagnostic test used to evaluate middle ear function by measuring the movement of the eardrum and the reflexes of the middle ear muscles. It involves the use of specialized equipment to measure the acoustic impedance, or resistance to sound, of the ear.
**Why the Correct Answer is Right**
The correct answer is the frequency probe, which is a type of probe used in impedance audiometry to measure the movement of the eardrum and the reflexes of the middle ear muscles. The frequency probe emits a range of frequencies to stimulate the middle ear muscles and measure their reflexes. This helps to assess the function of the middle ear and diagnose conditions such as otosclerosis or middle ear fluid.
*Option A* was not specified, so we'll move on to the other options.
**Option B:** This option is not correct because it does not specify a type of probe used in impedance audiometry. The tympanometer probe is used to measure the movement of the eardrum, but it is not the correct answer for the frequency probe.
**Option C:** This option is not correct because it does not specify a type of probe used in impedance audiometry. The acoustic reflex probe is used to measure the reflexes of the middle ear muscles, but it is not the correct answer for the frequency probe.
**Option D:** This option is not correct because it does not specify a type of probe used in impedance audiometry. The acoustic impedance probe is used to measure the acoustic impedance of the ear, but it is not the correct answer for the frequency probe.
**Clinical Pearl / High-Yield Fact**
The frequency probe is an essential tool in impedance audiometry, allowing clinicians to assess the function of the middle ear and diagnose conditions such as otosclerosis or middle ear fluid.
**Correct Answer:** C.
