Definitions

  • Protection against noise is the subject of much research. Increasingly stringent standards are imposed, in particular to provide effective protection for residents living on roads with high traffic density.
  • the present invention largely meets the requirements formulated in the most stringent standards. On the other hand, its assembly is easy and its maintenance, reduced to a minimum by its design and the choice of materials, is convenient, quick and does not lead, for residents, to a reduction in noise protection.
  • the noise barrier claimed in this invention is modular in design. It consists of two elements which fit into each other and conform to eliminate any air pocket and compress the absorbent material placed inside.
  • the screen (1) consists of an element perforated (2) profiled in a "U” shape and sliding, like a drawer, inside a box (3) serving as receptacle, open at both ends.
  • the absorbent material (4) protected by an envelope (5) waterproof and dustproof, is of a thickness slightly greater than the free space between the inner face of the perforated element (2) and the inner face of the box (3) so as to undergo a certain compression to eliminate any air pocket and prevent vibrations of the various components of the screen (1).
  • FIG. 2 shows a plan view of the screen (1) whose sides are closed over the entire height of the screen (1) by two clips (6) shaped to serve for fixing the screen (1) on end supports (7).
  • the joints (8) made of material of good sound insulation, of suitable shape and dimensions are interposed between the clam (6) and the box (3).
  • the screens (1) arranged one after the other are hooked to the end supports (7) so as to maintain perfect accessibility to each frame ( 6). Consequently, a continuous series of screens (1) can be formed by arranging them in a "staggered” fashion, in other words by attaching a screen to the front of the end supports (7) and by attaching the screen next to the back of the end supports, either "in a broken line” that is to say by hanging each screen so that, for example, the left end of the screen is at the front of the support end and that the right end is at the rear of the other end support.
  • Figure 3 shows a staggered arrangement
  • Figure 4 shows a broken line layout
  • Figure 5 shows a wall erected using these modular screens.
  • the noise protection walls constituted by the modular screens claimed in the invention have the advantage of offering an excellent absorption coefficient and consequently little sound waves are reflected towards the noise source. This wall therefore does not increase the noise perceived by people located in the area facing the protective wall.
  • the "staggered” or “broken line” arrangements give total accessibility to the absorbent material (4) without dismantling the box (3). In this way, even during the maintenance of the absorbent material (4), residents will continue to enjoy high level acoustic protection.
