Tympanometry is an examination used to test the condition of the middle ear and mobility of the eardrum (tympanic membrane) and the conduction bones by creating variations of air pressure in the ear canal.

BERA (Brainstem Evoked Response Audiometry) test is an otoneurological test that examines brain function and auditory function in response to the sound stimulus.
