The use of structure-borne sound is a promising method to identify and distinguish crash situations based on the structure-dynamic sound emission, which is generated within the initial milliseconds of the deformation. The wave propagation through the car body substantially contributes to the measurement system. However, their analysis and description via simulation methods is currently limited. An alternative strategy represents the propagation of structure-borne sound waves using a linear model approach. Experimental investigations on plates and selected car body elements complement the studies of wave propagation effects.
