Renault works on a concept of "acoustical mark", able to predict customer's sound quality perception. A subjective testing method was developed and carried out on economic cars to grasp both qualitative description of cars sound quality perception and quantitative information about how good the sound quality of a car is (a subjective mark). As main exploitation of the testing method and result of this work, let us quote the development of a computing able to predict the sound quality mark of a car as from its physical parameters. The sound quality mark tool will be applied at early stages during the development of new vehicles to help in the definition and the spreading of the acoustical objectives.
