Sound transmission between infinite rooms; a modal approach and fe-formulation

Jonas Brunskog, Peter Davidsson

Research output: Chapter in Book/Report/Conference proceedingArticle in proceedingsResearchpeer-review


A full description of the entire system room-wall-room in a theoretical model for sound insulation is still today too computation intensive, implying that the higher frequencies cannot be studied. Some simplifications must thus be introduced. The simplification proposed in the present paper is to replace the rooms with waveguides, i.e. infinity long rooms. The model then reduces to the (more or less) twodimensional wall. The question of how to apply the excitation then arises. The choice herein is to use a combination of diffuse field and Monte Carlo simulations. The incident and radiated power, expressed in the wave-guide modes, is used to calculate the transmission loss. A minor literature survey is also included.
