(54) Modular-type noise-insulating acoustic barrier and related manufacturing method


(57) 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.
