摘要： A noise barrier includes upright-standing support columns spaced a predetermine distance from each other and each made of an H section, and a plurality of wall panels provided between two neighboring ones of the support columns by inserting each wall panel at opposite lateral edges thereof from above into U-shaped recesses, opposite to each other, of the support columns, the plurality of wall panels being thus stacked one on another to form a main soundproof wall, and a noise control module to be installed on the topmost wall panel, the noise control module comprising side frame members to be inserted at lower ends thereof from above into the upper portions of the U-shaped recesses, opposite to each other, of the support columns; a lower frame member connecting the side frame members to each other by securing them at lower ends thereof to the lower frame member; first and second additional screens installed at lower ends thereof pivotably to the lower frame member and having a horizontal length smaller than the distance between the support columns; a coupling member holding the first and second additional screens at a predetermined angle of inclination when the additional screens are inclined toward and away from a noise source, respectively; and sound insulation joint sheets elastically extensible horizontally and bridging, over the support column, two additional screens put in neighboring relationship when the first and second additional screens are opened away from each other.
