Tympanometry varies ear-canal pressure and measures acoustic admittance, helping assess middle-ear effusion, perforation, or eustachian dysfunction.
Option by option
A. Measure cochlear nerve action potentials
Neural testing requires other audiology methods.
B. Assess middle-ear pressure and membrane mobility (correct)
Correct: it evaluates middle-ear mechanics.
