Tympanometry and Acoustic Reflex Testing

Tympanometry measures the function of the middle ear. A small soft probe is placed in the ear canal then the response of the ear drum to pressure changes is measured.

Acoustic Reflex testing measures a reflex arc that goes between the middle ear and brainstem in the auditory system which is elicited by an intense stimulus. These tests do not directly assess hearing ability, but are interpreted in conjunction with other test results.
