Document Summary

Myoelastic aerodynamic theroy elasticity of the vocal folds allows them to be set into vibration by aerodynamic forces (specifically the bernoulli effect) Caused by the increased speed of air passing between the vocal folds and. sucking motion of the vocal folds toward one another. Minimaul subglottal pressure for phonation (usually 3-5 cmh20)) Simultaneous onset simultaneous exhalation and abduction of vocal folds. Vocal rise time duration from onset to steady state amplitude. There is a disproportionately large increase in stress w/ more stretch. Strain length of change of tissue in direction of force. Fundamental frequency control of production of pitch by vocal folds. Large amount of air quickly: sudden change in frequency (voice break) Frequency and vocal folds lowest frequency: vfs most relaxed longer thicker vfs: lower voice. Lombard effect tendency to increase vocal intensity within high ambient noise levels. Only vf cover (epithelium, slp, ilp) vibrate during soft and high frequency phonation.
