4. Acoustic admittance: the reciprocal of acoustic impedance. The examination contents include: tympanic admittance test, tympanic muscle reflex, Eustachian tube function test. 5. Otoacoustic emission (OAE): like an "acoustic probe", it provides a window for clinic to directly understand the mechanical activity of cochlea, especially outer hair cells.

6. The tinnitus of acoustic neuroma is characterized by unilateral and high tone, such as cicada or whistle. In the initial stage, it was intermittent and gradually became persistent. Often accompanied by other neurological symptoms, such as headache, facial numbness.
