He has participated in committees on railway noise hosted by the Ministry of the Environment in Japan and contributed to publishing a prediction model of high-speed railway noise, manual for the measurement and evaluation of railway noise, etc.

 

Ard Kuijpers received his degree on Mechanical Engineering at the Eindhoven University of Technology (NL) in 1994 and his Ph.D. in 1999. He has worked at M+P since 1999 and is currently a senior consultant and managing director. He is responsible for all R&D activities at M+P. His professional interest lies in the vibro-acoustics of tyre/road and wheel/rail interaction: to understand the processes with the aid of physical and statistical modelling and machine learning and to develop dedicated measurement systems to characterize the sources and parameters that play a role in road and railway traffic noise. Besides working on the fundamentals of rolling noise and vibrations, he is active in the design and development of practical software systems to estimate, monitor, control and mitigate the impact on the society of noise and vibration from road and rail transport.
