ACTUAL QUESTIONS WITH VERIFIED
CORRECT ANSWERS. A+ GRADE
RATED
1. What is another name for volume velocity: Air flow
2. How do you calculate the average air flow (volume velocity): volume/time
3. What is a u-tube manometer: A tube in the shape of a 'U' that is used to
measure pressure and can be used to calibrate electronic equipment to measure
pressure.
4. How does a u-tube manometer work?: Pressure will displace the water and
the displacement can then be measured by measuring the difference in height
5. What is a u-tube manometer best used for?: Calibrations of equipment and
measuring static pressure
6. What are the limitations of a manometer: Measuring speech production
where the pressure goes up and down rapidly.
7. How do the rib cage and abdomen move as we speak: -inhale: rib cage and
abdomen expand
-exhale: rib cage and abdomen contract

, 8. What is subglottal pressure: Pressure that the lungs provide that go up the
trachea to the larynx.
9. What is subglottal pressure abbreviated as?: -P subscript s
-P subscript sub
10. Where is subglottal pressure measured?: directly below the larynx
11. How much subglottal pressure is enough for speaking?: normal speech: 5-
7 cmH2O
very loud speech: 15-20 cmH2O
12. What is phonation threshold pressure: The pressure needed from the lungs
to just get the vocal folds to oscillate to produce the softest voice
13. What influences phonation threshold pressure: -Dehydration -vocal
fatigue
14. How does dehydration influence phonation threshold pressure: if vocal
folds are dried out, they are less flexible and requires an increase in the
amount of pressure needed to make them move
15. How does vocal fatigue influence phonation threshold pressure: Vocal
folds become slightly swollen, which requires more pressure to get them to
oscillate. 16. What influences phonation threshold pressure in clinical
voice disorders: -folds are looser for easy onsets (less pressure needed)
-Folds are stiffer for harsh onsets (more pressure is needed)
-phonation threshold pressure will be higher for abrupt starts
- vocal fold lesions increase mass of vocal folds
-PTP is higher in many pathologies
