  • Patent number: 4805734
    Abstract: An acoustic wall for streets and parks and for garden-like designs consisting of several substantially U-shaped frame members arranged at a distance from one another, which frame members are connected among one another and have mats applied on their front and side surfaces. In order to substantially reduce the manufacture on location, the duration of setting up and the greening time on location, the acoustic wall consists of individual elements of which each has several U-shaped frame members which are secured at the ends of their long legs on a base. The base forms a rigid frame with fastening means for a lift for the lifting and transporting of the acoustic wall. One or several narrow-mesh mats are secured on the base, which mats prevent a falling out of material filled into the acoustic wall during transport.
