Exam 1 Part 11

Question 1

Number of cycles of vibration per second

Answer 1

Frequency (Hz)

Question 2

Given a constant volume flow of air or fluid, at a point of constriction there will be a decrease in pressure perpendicular to the flow and an increase in velocity of the flow

Answer 2

Bernoulli effect

Question 3

At the point of the constriction, the pressure will _____ and the velocity will ______

Answer 3

Decrease, increase

Question 4

Why is the Bernoulli principle important?

Answer 4

Negative pressures allow the vocal folds to come to the midline and positive pressures open the vocal folds

Question 12

The subglottal pressure must always be ____ for vocal fold vibration to occur

Answer 12

Positive

Question 13

If subglottal pressure is equal to atmospheric pressure what happens?

Answer 13

No phonation occurs

Question 14

Minimal amount of positive subglottal pressure needed to initiate and sustain vocal fold vibration

Answer 14
