Active Systems for reduction of sound emission and disturbing vibrations have been investigated on their suitability by research and development departments of big automotive companies for several years. Missing technologies for line production and present high expenses prevent the exertion in series-production vehicles. In the development cycle of products of future automotive generations, active systems can play a significant role yet. Based on the exertion of active systems as acoustic development tool of drive shafts, the following article explains how to use acoustic optimizing strategies by means of active systems.
