(54) Improved deadening barrier for highways, railways and the like


(57) A deadening barrier comprising an array of panels (P1,...,Pn), stacked and supported by fixed uprights (1) spaced from one another. Each panel comprises a first (3,23) and a second (7,22) containment sheet element having a substantially C-shaped section and facing each other, between which a layer (6,21) of material with high deadening coefficient is interposed. The containment element facing the noise source is uniformely perforated. The layer (6,21) is supported by first containment element (3,23) and second containment element (7,22) rests against the layer to hold it in position inside first containment element and support means (11,24) are provided for the second containment element and means (13,30) for blocking it between the support means and the panel support uprights.
