What is the cover body theory?
In 1974, Hirano published the cover-body theory of vocal fold vibration. Here he described the unique morphological structure of the vocal folds and divided them biomechanically into the body and the cover layer. The main substance of the vocal fold is the thyroarytenoid (TA) muscle.
What is the process of resonation?
The buzz created by the vocal folds resonates (vibrates) the air column and this in turn causes the structures above and around the larynx to vibrate/resonate as well. Remember from Phonation that the vocal folds vibrate and chop the air stream into little puffs of air.
What are the theories of phonation?
The myoelastic- aerodynamic theory of phonation maintains that vocal fold oscillation is determined by an interaction between aerodynamic stresses applied to the free surfaces of the vocal folds and myoelastic restoring forces gener- ated within the tissues.
What is vocal fold cover?
The vocalis and thyroarytenoid muscles make up the deepest portion. These vocal folds are covered with a mucous membrane and are stretched horizontally, from back to front, across the larynx.
What is the organ of phonation?
Phonatory System, also known as the larynx or “voice box”, where sound is produced includes: larynx and, specifically, the vocal folds (also called “vocal cords”).
How does the Bernoulli effect help phonation?
The Vocal Folds Open during breathing, the folds are closed by the pivoting of the arytenoid cartilages for speech or singing. Positive air pressure from the lungs forces them open momentarily, but the high velocity air produces a lowered pressure by the Bernoulli effect which brings them back together.
What is the Bernoulli principle used for?
Bernoulli’s principle is used for studying the unsteady potential flow which is used in the theory of ocean surface waves and acoustics. It is also used for approximation of parameters like pressure and speed of the fluid.
