During fonation the vocal folds are excited by air flow. This air is portioned by vocal folds into separated air bubbles. These are the cause of the source voice. It is obvious, that we must model fluid-structure interaction. Actual models comes from air flow hypothesis, and the influence of Bernoulli's effect. Next thing is, that as agitated medium is mostly used incompressible fluid. The idea of this new model is to molel function of vocal folds as full fluid-structure interaction. As agitated medium is used compressible air with laminar flow option. Simulacion was computed by FEM program Ansys 8.1.
