ASLP 3030: TEST 2 Exam Questions and
Answers 100% Pass | Already Graded +
What is a U-tube manometer and what does it measure? - ✔✔- Used for
people to blow air in the manometer to move the water on the other side of
the manometer
- measures the force (the air pressure) that is required to move water,
cmH2O
How does intraoral air pressure differ for a stop and/or fricative consonant
vs. a vowel consonant? - ✔✔-For vowels the pressure is the same fro your
mouth and the microphone
- For fricatives you have to build pressure behind constriction, will be
elevated
- For stop consonants the pressure is the highest because you close the
vocal tracts and releasing the highest amount of pressure built.
Which sound has intraoral pressure that is roughly equal to atmospheric
pressure? - ✔✔Vowel consonants
, What is subglottal pressure? - ✔✔-The amount of energy that you can
generate below your vocal folds (larynx)
- the driving pressure for phonation and speech
-hard to measure
Which sound has intraoral pressure that is roughly equal to subglottal
pressure? - ✔✔bilabial plosive /p/
What value of subglottal pressure is normal when speaking at a typical,
conversational volume? - ✔✔5-7 cmH20
What is phonation threshold pressure? - ✔✔-the amount of pressure that is
required from the lungs in order to get the vocal folds to oscillate at the
safest a person can produce
- need 3-5cmH20 to start vibrating
- PTP increases with dehydration (wont be able to produce oscillation at a
low level) and vocal fatigue (get swollen, puffy, and bulky, need more
pressure to vibrate)
Why would phonation threshold pressure be higher in speakers with voice
disorders? - ✔✔- folds are looser for easy onset
- folds are stiffer
- threshold pressure will be higher for abrupt start
