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 9. The ratio of vibrational amplitude to vocal-fold length is about 0.5.
