Ride comfort is defined as the overall comfort and well-being of the vehicle’s occupants during vehicle travel. The main sources of discomfort are oscillations which reach the vehicle’s passenger compartment and cause noise, vibration, or both. Since the sources of these oscillations (the roadway, chassis, and powertrain) are outside of the passenger ...

CLUSTERING INVERSE BEAMFORMING FOR VEHICLES NVH
24th International Conference on Sound and Vibration 2017, London CallingClustering Inverse Beamforming is an array-based acoustic imaging technique to solve inverse problems formulated by discretizing the source region into elementary equivalent sources. It is based on a statistical processing of multiple realizations of the acoustic image, related to the investigated source region, iteratively obtained solving the ...
