Auralization of road noise CAE simulation results for interactive sound quality evaluations

Abstract

Road noise is one of the dominant contributions to a vehicle interior noise when driving below highway speed. In this paper, we present the process we developed to support automotive OEMs with road noise engineering during vehicle design and development. The process allows to auralize, in a driving simulator for NVH, road noise CAE simulation results obtained from coupled multibody, structural finite-elements and acoustic models. With this process, engineers can now listen to a vehicle sound and perform interactive sound quality evaluation for road noise even before physical prototypes are available.
