Mise au point aéroacoustique des véhicules chez PSA

Vehicles aeroacoustic perfecting at PSA

P.S.A. Peugeot Citroën

Abstract

Due to the increasing importance of acoustic comfort in vehicles, car manufacturers have developed their knowledge and methodologies in automobile aeroacoustics. After having achieved a better understanding of theoretical aerodynamics and acoustics relationships, carmakers have applied it to settle new development methods and techniques. Thanks to these new measurement methods in new low background noise aeroa-coustic windtunnels, great improvements have been obtained, particularly on outer devices like rearview mirrors, windshied wipers... Further developments will be done in two directions: computational aeroacoustics and psychoacoustics.
