Finite Element Approximation of Eigenvibration of a Coupled Vibro-Acoustic System Motivated by Phonation into Tubes
Original language description
The mathematical model of the vibro-acoustic problem rep- resenting human phonation into tube is formulated. It consists of acoustic and structural problem description as well as their mutual coupling. Here, the vocal folds vibrations are modelled using linear elasticity theory and the Helmholtz equation is used for frequency characterization of acoustic waves propagation in the vocal tract model. The both subproblems are numerically approximated by finite element method. The preliminary results compare the acoustic eigenfrequencies of vocal tract with tube and the eigenfrequencies of the coupled vibro-acoustic system. The eigenmodes with significant acoustic contribution are identi- fied. The first eigenfrequency of coupled system with prevailing acoustic part is substantially increased indicating strong interaction with the elas- tic structure.
