Abstract

PROCEDE PERMETTANT D'AMELIORER LA LUTTE CONTRE LE BRUIT, EMIS PAR UNE SOURCE SONORE, QUE CELLE-CI SOIT UN FLUIDE, UNE MACHINE, UN SYSTEME OU UNE STRUCTURE EN MOUVEMENT. LE PROCEDE CONSISTE A REALISER L'ENVELOPPE 2, SERVANT DE SUPPORT DE BASE A UN FLUIDE, UNE MACHINE, UN SYSTEME OU UNE STRUCTURE EN MOUVEMENT 1, EN LUI DONNANT UNE EPAISSEUR VARIABLE 4, A L'AIDE D'UN MATERIAU HOMOGENE OU NON 5. SA SECTION DROITE, FORMEE PAR LE PERIMETRE INTERNE ET EXTERNE DE L'ENVELOPPE, PRESENTERA L'ASSOCIATION DE DEUX FIGURES GEOMETRIQUES DIFFERENTES PAR LEUR DIMENSION OU LEUR TRACE 6. CETTE TECHNIQUE S'APPLIQUE A DIMINUER EFFICACEMENT LE BRUIT EMIS PAR UN FLUIDE, DONT ENTRE AUTRES L'AIR OU L'EAU EN MOUVEMENT, PAR UNE MACHINE TOURNANTE OU D'UNE FACON GENERALE EN MOUVEMENT, TELS QU'UNE HELICE, UNE TURBINE, UN MOTEUR, UN COMPRESSEUR, ETC.
