Název v původním jazyce

Finite element modelling of the effect of lamina propria properties on vocal-fold vibrations and produced sound

Popis výsledku v původním jazyce

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. The effect of lamina propria thickness and material properties on simulated videokymographic (VKG) images of vocal-fold vibrations and produced sound spectra is analyzed. The developed FE model includes large deformations of the vocal-fold tissue, vocal-fold contact, fluid-structure interaction, morphing the fluid mesh according to the vocal-fold motion, unsteady viscous compressible airflow described by the Navier-Stokes equations and airflow separation during the glottis closure. The developed FE model can be used to study relations among pathological changes in vocal folds tissue,the resulting VKG images and the produced sound spectra.
