1 AAC 2014 Development and Research in AUTOMOTIVE ACOUSTICS PROGRAM BOOK November 24 26, 2014 Pullman Aachen Quellenhof, Germany

2 Foreword 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, Forschungsgesellschaft 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. Organizers FEV GmbH Forschungsgesellschaft Kraftfahrwesen mbh Aachen HEAD acoustics GmbH Institut für Technische Akustik, RWTH Aachen University
