<p>The wall (1) has a supporting stone (2) made of heavy concrete, where the supporting stone possesses an elevation surface (4) made of natural stones (5). A sound absorption layer (3) made from lightweight concrete connects the elevation surface with the supporting stone over an adhesive bond. The natural stones are arranged in a bidirectional flow layer before the sound absorption layer that is designed as a lightweight aggregate concrete shell. An independent claim is also included for a method for manufacturing of a noise protection wall.</p> |
