AlphaCell by Matelys



Simulate the Vibro-Acoustic Response of Multi-Layer Trims Using the Complete and Accurate TMM/FTMM Solution

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.
