| Summary: | The significance of taking into account non-locally reacting behavior of boundaries compared to the often-used locally reacting assumption in room acoustics has not been extensively investigated. To make this possible a boundary element method is developed, inspired on a seismic simulation method known as the WRW method. The novelty of this method compared to other boundary element methods (BEM) is that the calculation is performed in only one domain. There is no need for a fluid-structure coupling, which in general allows faster simulation times. The theory of the method is presented and some example structures are simulated with both locally and non-locally reacting behavior. The results are shown and discussed. |
