Finite element modelling of the effect of stiffness and damping of vocal folds layers on their vibrations and produced sound
Original language description
The study presents a two-dimensional (2D) finite element (FE) model of the fluid-structure-acoustic interaction during self-sustained oscillation of the human vocal folds (VF). The FE model combines the FE models of the VF, trachea and a simplified human vocal tract shaped for phonation of a Czech vowel [a:]. The developed FE model comprises large deformations of the VF tissue, VF contact, fluid-structure interaction (FSI), morphing of the fluid mesh according to the VF motion (Arbitrary Lagrangian-Eulerian approach), solution of unsteady viscous compressible airflow described by the Navier-Stokes equations and airflow separation during the glottis closure. The effect of stiffness and damping of lamina propria, which can be caused by certain VF pathologies, on VF vibrations and produced sound are analyzed.
