It is disclosed an anti-noise panel comprising a front shell and a rear shell that are coupled together within which rubber elements of specifically designed shape and size are incorporated. Said panel can be advantageously obtained by using also recycled, injected thermoplastic material, that allows the resulting panel to be conveniently used when the wind causes strong impact, for example, along railway lines where the compression waves generated by trains traveling at high speed over time tend to disassemble the riveted aluminum/steel sound barriers currently in use.
