Foreword

Aachen is one of the most important centers for development and research in automotive acoustics. This year, the Aachen Acoustics Colloquium takes place for the sixth time under the aegis of Prof. Dr. S. Pischinger, FEV GmbH, Prof. Dr. J.-W. Biermann, Forschungsgesell-schaft Kraftfahrwesen mbH Aachen, Prof. Dr. K. Genuit, HEAD acoustics GmbH, and Prof. Dr. M. Vorländer, Institute of Technical Acoustics of RWTH Aachen University.

In the context of the Aachen Acoustics Colloquium, recent methods and technologies within the field of acoustics and vibrations of vehicles and drives are presented and discussed in detail in 23 dedicated papers and presentations.

Program 24.11.2014

The continuous and free exchange of ideas between colleagues and experts, working in both industry and research, will ensure that consumers will keep finding attractive vehicles with an appealing sound.
