摘要： A noise attenuation barrier for control of noise along expressway or other noise sources is provided in which the panel sections are suspended on vertical posts installed in earth berms. The bottoms of the panels, which are shaped to match the contour of the berm are partly buried in a particulate, sound-absorbing layer. The panels include an imperforate rear wall, spaced away from which is a sound-absorbing layer held in place by edge strips that are fit over the tops and bottoms of the layer before it is put in place.
