This quiz consists of 10 multiple choice questions.  The quiz must be completed once started and you will have a one hour time limit.  There will be feedback for incorrect answers.  You will also be able to go back in a review the quiz. The quiz is due by Sunday September 22.

Q: A tympanogram is an assessment of _________ function.
- outer ear
- middle ear
- inner ear
- none of the above
A: middle ear
If wrong: A tympanogram represents middle ear function.

Q: An abnormally small physical volume means:
- a possible eardrum perforation
- the equipment isn't functioning properly
- the probe tip is against the earcanal wall
- either a or c
A: the probe tip is against the earcanal wall
If wrong: the probe tip is against the earcanal wall

Q: The Type C tympanogram indicates the middle ear has abnormal
- positive pressure
- negative pressure
- normal pressure
- either a or b
A: negative pressure
If wrong: abnormal negative pressure

Q: The definition of static compliance is:

- the width of the tympanogram
- the amount of positive pressure measured
- the amount of negative pressure measured
A: the height of the tympanogram at it's peak
If wrong: the height of the tympanogram at it's peak

Q: An acoustic reflex is the involuntary contraction of the:
- stapes muscle
- tympanic membrane
- eighth nerve muscle
- stapedius muscle
A: stapedius muscle
If wrong: the involuntary contraction of the stapedius muscle

Q: Tympanograms are categorized into five basic categories called:
