Titel:
Modal based model reduction techniques for FSI-problems in room acoustics 
Abstract:
In room acoustical simulations energy-methods often are used to predict the sound-field in closed volumes. Those methods are robust for subsystems with high modal density. However, their performance is limited if the spatial resolution of the response is of interest or if complex boundary conditions (e.g. plate resonators or passive absorbers) have to be considered. Numerical methods like the Finite Element Method (FEM) or the Spectral Finite Element Method (SFEM) are used for this task. The ord...    »
