The Bernoulli Effect at the Glottis Pulls the Folds Closed
The second ingredient of the theory. Air accelerating through the narrow glottis drops in pressure, which pulls the folds back toward each other. Taught separately from subglottal pressure because it is a different physical claim, and because students routinely believe the folds are actively opened and closed by muscle on every cycle, which this node is built to refute.
Questions this Concept answers
- The myoelastic-aerodynamic account denies that muscle contraction closes the vocal folds on each cycle. What does it put in place of that contraction?
The Vocal Fold Mucosal Wave in Voice Production Physiology
Human voice production results from vocal fold vibration driven by the interaction of subglottal air pressure, muscle-controlled adduction/abduction, tissue elasticity, and the Bernoulli effect, prod…
