Prof. Dr.-Ing. Alexander Zopp studied mechanical engineering at the Technical University of Darmstadt. He received his PhD in 2000 in the field of finite elements in acoustics. He then joined Adam Opel AG to work in the Vehicle Simulation Department. In the NVH group he analyzed vehicle vibration and vehicle acoustics with the FEM. Later, Mr. Zopp introduced the Statistical Energy Analysis (SEA) in the development process of Opel to expand the detectable frequency range in the simulation. He was responsible for the global simulation methodology in the high frequency range in the GM group. Since 2011, Mr. Zopp served as Group Head of NVH simulation at Opel. Since 2013 he has been a professor at the RheinMain University of Applied Sciences and lectures in the subjects finite elements, engineering mechanics, machine dynamics and NVH.

Prof. Dr.-Ing. Dietmar Jennewein studied mechanical engineering at the University of Kaiserslautern. He received his PhD in 1998 in the field of vibration technology. He then joined the Adam Opel AG in the "Vehicle Simulation" department and worked in the NVH group on the analysis of vehicle vibration and vehicle acoustics using the FEM. Since 2001, Mr. Jennewein was responsible as a group leader for all NVH simulation activity at Opel. He also led a multidisciplinary team for the metrological validation of the calculation procedure. Since 2011 he has been a professor at the University of Applied Sciences Darmstadt and lectures in the subjects of engineering mechanics, control and automotive engineering.
