Description
A recently started research project brings together experienced research teams from Czechia, Germany and Austria to expand the knowledge on the nature of the mucosal wave which is important for (1) improving the accuracy of the mathematical and physical models of voice production, and for (2) more insightful diagnosis of voice disorders. Based on experimental observations, kinematic laws will be derived to inform and drive mathematical models of VF oscillation, enabling them to accurately reproduce the observed mucosal behaviour. These models will subsequently be applied to investigate the aeroacoustic mechanisms underlying voice production. Furthermore, the ex vivo characterization of MW kinematics will guide the optimization of geometric and structural parameters of a novel self-oscillating silicone VF model incorporating an embedded liquid layer, designed to better replicate physiological conditions. In parallel, computational models of self-sustained VF oscillations incorporating fluid-structure-acoustic interaction will be refined to improve their ability to simulate MW dynamics. The presentation will include an overview of the research project and will highlight first results towards the numerical simulation of the generation of human phonation taking into account the full fluid-structure-acoustic interactions.
