- Abstract:
- The prediction of structure borne sound in vehicles or buildings and the related sound fields in the acoustic volume is typically carried out either with a Finite Element (FEM) approach or with the help of energy methods like the Statistical Energy Analysis (SEA). Whereas the first method is limited to lower frequencies the SEA is appropriate for frequency ranges, where the structures have a high modal density and the system´s behaviour is dominated by resonant vibrations.
