Case 2 Immittance

□       List the tympanogram types.  What do they suggest about the middle ear? Do they correlate with the audiometric results?

□       Characterize the acoustic reflex thresholds: present at normal or elevated hearing levels?

□       Calculate the sensation level of the 500 Hz left contralateral reflex and the 4000 Hz left contralateral reflex.

□       Are the reflex patterns suggestive of cochlear or retrocochlear pathology, or ambiguous?
