A sound barrier system particularly suited for out-of-doors, ground-mounted installations, such as for a highway noise barrier, comprises a vertical wall composed of successive individual wall sections arranged with immediately adjacent wall sections disposed at an intersecting angle to each other. Immediately adjacent wall sections are rigidly joined together in abutment along a common vertical joint. An earth anchor is anchored into the ground at each vertical joint. Each joint is secured to the corresponding earth anchor so that downwardly directed hold-down forces are applied by the earth anchors to the wall at the bottom portions of the joints.
