Résumé

Compte tenu de la reconnaissance par l’industrie d’automobile de l’importance de la perception des émissions de NVH, il y a maintenant plus de concentration sur la qualité sonore du bruit à l’intérieur des automobiles. L’analyse psycho-acoustique a été effectue avec l’aide des mesures des pressions acoustiques à l’intérieur du véhicule. Les mesures des vibrations de la suspension de l’automobile ont été prises à plusieurs positions structurelles pour évaluer les excitations de vibration. En utilisant les données de bruit et de vibrations, il a été possible d’évaluer le moyen de transfert de l’énergie d’excitation de la suspension à l’intérieur du véhicule. Une tentative d’établir une corrélation entre les mesures de bruit et de vibrations et les observations psycho-acoustiques a été possible avec certaines limites.
