2. In the vocal folks, stress and length tend to vary at the same time whenever either is changed.
True
False

3. The amplitude to length ratio of the vocal folds is .001; as a result changes in lung pressure have little effect on fundamental frequency.
True
False

4. Vocal fold length is the primary variable for adjustment of fundamental frequency.
True
False

5. The vocal ligament plays no role in regulating passive stress in the vocal fold.
True
False

6. In general, there is an increase in fundamental frequency with an increase in lung pressure, and this increase is greater for high notes than for low notes.
True
False

7. Fundamental frequency is related to pitch and is precisely the inverse of the period.
True
False

8. Dynamic strain is a measure of how much longer straight fibers are than curved fibers.
True
False
