Abstract (en)
[origin: WO9837276A1] The invention relates to a sound protection device for reducing the propagation of airborne sound, comprising a track system and an elastically deformable, low sound-protecting wall (5) made of rubber or plastic and extending in the longitudinal direction of the track. Said sound-protecting wall is arranged at a distance to the track (1) and on the side facing the track (inner side, 6) has a profile which essentially extends across the entire height of the wall. The side of the protecting wall facing away from the track (outer side, 7) has a generally even surface. According to the invention, the inner side (6) is inclined at an angle alpha and the outer side (7) at an angle beta to the track (1), whereby angle beta is greater than angle alpha . The profile of the inner side (6) consists of a system of lips (8), which lips point towards the floor (4) of the track at an angle gamma . The top of the low sound-protecting wall (5) ends in a lip (9) inclined towards the track (1), which lip points upwards at an angle delta . In addition, the low sound-protecting wall (5) comprises at least one hollow chamber (10) extending in the longitudinal direction of the track.
