Computationaly eficient approach for modeling the acoustic of 1D models with branching of the structure

Popis výsledku v původním jazyce

The work describes the procedure of modeling the acoustics of 1D models. The procedure combines analytical procedures and discretization and it is an alternative to the finite element method. The resulting models are computationally efficient and are therefore suitable, for example, for optimization tasks. The strong point of this method is the possibility of arbitrarily branching a 1D model. The model solves a modal problem. It is possible to find an unlimited number of natural frequencies and waveforms regardless of the discretization used. Furthermore, it is possible to perform a simulation of steady state oscillations excited by a boundary condition. The geometrically very complex human vocal tract was modeled using the described procedure. The results are in agreement with the physiological values. Furthermore, a comparison of calculation speed and results with the finite element method was performed on a simple geometry.
