Abstract (en)
[origin: EP0527115A1] A soundproofing and sound-deadening board modular unit for antinoise barriers, said unit comprising a first metallic hull 2B which is exposed to the source of noise, a second metallic hull (3B) performing the function of a cover or lid, and a sound-deadening member of tight-seal, modular type, which is realized with a first layer (7B) of an impermeable film, of a polyurethane -type membrane, a second layer (8B) consisting of a high-density sound-deadening separation wall, and a third layer (9B) consisting of a low-density mattress, said first, second and third layer, being reciprocally joined by means of a hot-pressing process, and said sound-deadening board being fastened by a fixed joint within a cavity that is defined at the points corresponding to the upper and lower edges of said first and said second metallic hull. <IMAGE>
