    摘要: - Ce mur absorbant les sons a une structure de résona teur.
    - Il est constitué d'au moins trois panneaux en béton, en terre cuite, en fibro-ciment, en matière plastique, ou en toute autre matière facile à entretenir, dont le premier est percé d'ouvertures, le second et éventuellement les autres, sauf le dernier, sont également percés d'ouvertures, mais de plus petites dimensions, tandis que le dernier est entièrement plein, ces panneaux ayant leurs côtés latéraux engagés dans des glissières verticales, en forme de U, prévues dans des piliers successifs.
    - Ces murs peuvent notamment protéger les riverains des autoroutes contre le bruit provoqué par la circulation sur lesdites autoroutes.

    摘要: O A sound damping wall often causes vibration hindrance unless a ditch of sufficient depth is dug at the rear side. This is not longer necessary if a wall according to the invention is used. Said wall consists of multiplex contained in azobe, while the connecting means, with which the panels are attached to posts, have in the case of loading parallel to the surface of the panels, a greater thickness in the direction perpendicular to the panels. The connecting means are preferably metal clamping frames having a bevelled U-shaped cross-section.

    摘要: @ A sound insulating device which can be of small volume and is for installation in means intercommunicating two spaces to reduce sound propagation between the two spaces while allowing air or gas exchange therebetween, comprises a container (1) having first and second openings (6) and (10) respectively communicating the interior of the container with the two spaces, sound absorbing means (8) attached to an internal surface of the container and sound converging means (7; 13, 14; 16) for causing a sound wave entering the container from the first space to converge at a predetermined location (P) in the container, the second opening (10) of the container (1) being offset with respect to the predetermined location (P).
