Phonation
Linked via "pulmonary pressure"
Aerodynamics and Laryngeal Configuration
The initiation and maintenance of phonation rely on a precise balance between pulmonary pressure (the driving force) and the mechanical properties of the vocal folds (the resistance). This relationship is formalized in the Laryngeal Impedance Equation ($\text{LIE}$), though empirical measurements often deviate due to mucosal drag effects [6].
