Assessment of 3D elasticity data of the larynx for FE models of phonation
Résumé
The quality of numeric models of phonation is strongly dependent on the accuracy of geometric and elastic tissue data because of the inhomogeneous and anisotropic nature of these structures. The dynamic elasticity of the vocal folds can be assessed in vivo and in vitro with a linear skin rheometer. This method has been applied in parallel and normal to the vocal fold surface of excised larynges. The data was collected in several directions and for two layers of the tissues which provides a base for a finite-element model. The results of the measurements are presented and consequences for the simulations are discussed.
