<p>The wall has a set of plate-shaped absorption units (3a, 3b) fastened independent of each other at two opposite sides of a frame (2) by a common elastomer damping unit. The absorption units are manufactured from timber, and are arranged at a distance from each other in a set of parallel planes (4a, 4b). A layer (5) of damping materials such as mineral wool, is arranged between the absorption units of the individual planes, where the absorption units and the damping unit are arranged in a common plane.</p> |
