Myoelastic-Aerodynamic Theory of Phonation

5

in the open phase or diverging glottal configuration the air pressure is less than during the converging g.c., elasticity with the static positioning of the open phase begin to draw the folds back together

3

pressure overcomes the resistance forcing the folds apart and releasing one puff or air

4

release creates a sudden drop in pressure at the level of the folds

2

sub-glottic air pressure builds against the resistance of the approximated folds

6

the closed phase occurs as the vocal folds approximate or converge and the process repeats itself

1

vocal folds adduct and approximate at the midline

theory

-most widely accepted theory of voice production -describes voice production as a combination of muscle force (MYO), tissue elasticity (elastic), and air pressures and flows (aerodynamic)
