Original Abstract

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. Such variation of the lamina propria properties can be caused by certain vocal-fold pathologies such as Reinke's edema. Numerically simulated VKG images show close similarities with those observed laryngoscopically in vivo. 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.
