Noise absorbing wall element consists of a flat base (1) which bears on the face two each other across guided systems of rails (3, 4) where the rails of each systems are arranged in relative spacing and in fact perpendicular to the base (1) so that the section of both systems of rails (3, 4) through plane parallel to the base (1) has the form polygonal network, whereby between the base (1) and two systems of rails (3, 4) is a layer (5) of the sound absorbing material . Between the base (1) and layer (5) of the sound absorbing material is created the air gap (7). From the manufacturing point of view it is advantageous to arrange the system of rails (3, 4) into sub-blocks (2) which are each ranked above the other and / or side by side. Base (1) can be equipped with means for mounting on the bearing elements and / or means for interconnection of elements. |
