What are the main components of an acoustic immittance tester?

An acoustic immittance tester primarily assesses the impedance and admittance of the ear, which provides valuable insight into the status of the middle ear and overall auditory function. The main components of an acoustic immittance tester include a balance meter, which measures the impedance of the system; a potentiometer, which allows for the adjustment of voltage and aids in calibrating the device; and a manometer, which measures air pressure within the ear canal. Together, these components work to analyze how sound moves through the middle ear, ultimately assisting in diagnostic procedures related to hearing health.

The other choices involve components associated with different types of auditory measurements or testing methodologies and are not relevant to acoustic immittance testing specifically.
