ACOUSTIC ATTENUATION DEVICE FOR RAILS
An acoustic attenuation device for a rail (100), comprising a vibration-damping profile (2) having a substantially "C"-shaped cross-section apt to be applied under said rail (100), with a first contact surface (3) facing a base surface (4) of said rail (100); a closure plate (20) having a plurality of holes (21) and defining a cavity (5) internal to said vibration-damping profile (2); a sound-deadening element (10) placed inside said cavity (5); and means (30, 31) for anchoring the device to said rail (100), wherein said vibration-damping profile (2) is made of recycled polymeric material.
