Abstract
Abstract A noise absorbing element capable of being vertically stacked and/or attached to vertical members includes a tube which is rectangular in cross-section which forms the front, back and side walls of the element. One or more partitions and/or spacing elements are located inside the tube and divide the interior thereof into at least a front cell and a rear cell. The front cell is closed at the bottom and is filled with a sound absorbing material such as glass or rock wool. For vertically stacking, the upper or lower end of the tube terminates in an annular channel which is adapted to receive the corresponding upper or lower end of the next adjacent barrier element.
