The Myoelastic-Aerodynamic Theory of Voice Production is a fundamental concept in vocal physiology. It explains how vocalization occurs through the interaction of muscular forces and airflow. In the theory the vocal folds adduct, sub glottal air pressure builds, air pushes the vocal folds apart until the force of the muscle elasticity is greater than the air pressure, the vocal folds move back together with the help of the Bernoulli effect, and the cycle starts over.
