The rapidly progressing development of new function-integrating lightweight structures leads to an increasing use of weight reduced solutions with high performance composites. Here, the growing customer demands on comfort and safety require not only high specific lightweight properties but also reduced vibrations and sound radiation. The complex interaction of frequency, damping and mass effects on the radiated sound power of lightweight composites and sandwich structures requires a case-by-case evaluation. Depending on the main goal of the design process, the developed optimisation tool enables the engineer to quickly find an optimal material lay-up.
