Acoustic damping for railway

摘要

To give an acoustic damping for a railway permanent way, a cladding with openings is laid between and/or next to the rails using elastic plates (5,6) of bonded rubber granules. It has openings (7) in a truncated cone shape, open upwards, tapering down to the track support plate (1). The plates (5,6) are bonded to the track support plate (1) by a polyurethane based adhesive.
