Reducing Pass By Noise of Renault Megane III – Results from the EcOBEx project

This webinar presents the work carried out during the EcOBEx research project for the reduction of the pass-by noise of a Renault Megane III 1.5 dCi, as measured according to the new R51-03 standard. This work enables to reach a measured 5dB reduction of the powertrain contribution on the pass-by noise levels for an iso-mass compared to the existing one.
