QUANTIFYING THE ELASTICITY OF MECHANICAL VOCAL FOLDS REPLICAS

International audienceThe mechanical properties of two types of deformable mechanical vocal folds replicas are considered. On one hand, the linear elasticity of multi-layered silicone vocal fold replicas with constant elasticity is considered. On the other hand, the mechanical properties of pressurised latex tube replicas with variable elasticity are assessed. In order to quantify the elasticity of these VF's and their influence on the fluid-structure interaction underlying sustained auto-oscillation, experimental as well as model results are presented. This way this work contributes to customised VF replicas with predicted and quantified elasticity
