THEORIES OF PHONATION

 

MYOELASTIC AERODYNAMIC THEORY

Definition

ONE EXPLANATION OF HOW VOCAL FOLDS VIBRATE:

BERNOULLI EFFECT: 

*VOCAL FOLDS PUSED APART, THEN PULLED BACK

  TOGETHER BY NEGATIVE AIR PRESSURE FLOWING

  THROUGH CONSTRICTION

*STATES WHEN GAS OR LIQUID BLOWS THROUGH OR

  AROUND A CONSTRICTION VELOCITY INCREASES,

  WITH INCREASE IN VELOCITY THERE IS A DROP IN

  PRESSURE

*VOCAL FOLDS PUSHED APART, ELASTICITY OF TISSUE
