Abstract

Anti-noise wall intended to block the propagation of sound waves, the said wall consisting of panels incorporating acoustically insulating elements, the said panels being connected to each other by posts (13) anchored to the ground, characterised in that the posts have a substantially U-shaped cross-section, including a cross-piece (131) and two side wings (132), the said panels being attached to the posts on their side wings. The internal volume of the posts is preferably filled with an acoustically insulating material which may be sand.
