Current UN ECE vehicle noise regulation requires a demanding reduction of the overall noise level emitted to the outside to the benefit of the health of citizens and road users. New limits have been implemented in the UN R51 Regulation to reduce noise. To achieve these goals, car manufacturers need to refine their vehicle set-up, and a purely experimental approach may come too late. This article shows a method for simulating pass-by noise that exploits numerical transfer functions and a library of experimentally characterized sources with the aim of reducing noise and finding a better compromise between costs and effectiveness of the modifications. In addition, a simple software tool was created for data processing and to facilitate the workflow, used for the evaluation of the rank of the different paths.
