What is myoelastic/aerodynamic voice production?
Janwillem van den Berg, noted Dutch scientist and researcher, in his seminal article “Myoelastic-Aerodynamic Theory of Voice Production” (Journal of Speech and Hearing Research 1: 227–244, 1958), convincingly promulgated the hypothesis that vocal-fold vibration is produced by the coordination of muscle tension and breath pressure. He did so in rejoinder to Raoul Husson's neurochronaxic principle, which suggested vocal-fold vibration is determined by events initiated by rapid excitation of cells of the recurrent nerve that consequently place the vocal folds into vibration. Van den Berg declared the now generally accepted premise that the vocal folds provide a muscle (myoelastic) response to airflow (aerodynamic) events. In contrast to nonvoiced sound, voiced phonation in speaking and singing is dependent on the vibratory action of the vocal folds in response to airflow that sets them in motion.
Much of voice pedagogy is directed to the adroit coordination of the vibrator (larynx) and the motor (breath mechanism). A reliable breath-management technique assures proficient myoelastic-aerodynamic collaboration for the tasks of
