Abstract (en)
Noise-insulating acoustic barrier formed by panels (10) comprising a mass of sound-absorbing material (17) arranged between two C-shaped profile sections (16) that are inserted between the flanges of I-shaped risers (11). <??>Pairs of fretted plates (14) enclose said panels on their front and rear sides and have their edges joined to each other by means of an alternate overlapping pattern. <??>The barrier is easy to manufacture directly on the site of installation. <IMAGE>
