Abstract: A vibrating element on an elastic foundation in the wall of a channel conveying air approximates the vocal fold oscillations. The viscous incompressible 1-D fluid flow theory is used and a generally defined shape of the vocal fold is considered. The numerical solution yields the instability thresholds, which are close to the known physiological data for phonation thresholds. The viscosity is important for very small opening of the glottis where its effect on instability boundaries increases.
Keywords: aeroelastic instabilities; biomechanics of voice; phonation thresholds
