Title (EN) TRANSPORTATION VEHICLE SOUND INSULATION PROCESS AND DEVICE
(FR) PROCÉDÉ ET DISPOSITIF D'ISOLATION ACOUSTIQUE D'UN VÉHICULE DE TRANSPORT
Abstract:
(EN) A sound insulation process comprises (a) providing at least one sound insulation device comprising at least one sound barrier comprising at least one substantially periodic array of structures disposed in a first medium having a first density, the structures being made of a second medium having a second density different from the first density, wherein one of the first and second media is a viscoelastic medium having a speed of propagation of longitudinal sound wave and a speed of propagation of transverse sound wave, the speed of propagation of longitudinal sound wave being at least about 30 times the speed of propagation of transverse sound wave, and wherein the other of the first and second media is a viscoelastic or elastic medium; and (b) interposing the sound insulation device between an acoustic source area and an acoustic receiving area of a transportation vehicle.
(FR) Un procédé d'isolation acoustique consiste (a) à fournir au moins un dispositif d'isolation acoustique comprenant au moins une barrière acoustique comprenant au moins un réseau sensiblement périodique de structures disposées dans un premier milieu ayant une première densité, les structures étant constituées d'un second milieu ayant une seconde densité différente de la première densité, l'un des premier et second milieux étant un milieu viscoélastique ayant une vitesse de propagation d'ondes acoustiques longitudinales et une vitesse de propagation d'ondes acoustiques transversales, la vitesse de propagation des ondes acoustiques longitudinales étant au moins 30 fois supérieure à la vitesse de propagation des ondes acoustiques transversales, et l'autre des premier et second milieux étant un milieu viscoélastique ou élastique ; et (b) à interposer le dispositif d'isolation acoustique entre une zone formant source acoustique et une zone de réception acoustique d'un véhicule de transport.
