The goal of this research is to predict how main noise-causing components contribute to the exterior noise level, without having to physically integrate them in the truck. Road transportation noise is a growing source of concern. Legislations define pass-by noise test procedures according to which vehicles need to be tested. In the European Union, the noise emission limit is set by directive ECE-R51.03 [1]. The ISO standard has recently been updated, defining a more constrained test procedures that better reflect the reality of urban traffic noise [2]. At the European level, a plan has been set to lower noise limits in the next years.
