    摘要: Elastic band-shaped base (1) made of rubber or of a material similar to rubber for insulating and absorbing vibrations and impact sound, specially track-bed matting, wherein the base is fitted with spaced tubes (2, 3) running parallel to the ground side (4) of the base on at least two planes (I, II). The tubes have a semicircular, semi-oval, or semi-ellipsoidal cross section. The invention is characterized in that two planes (I, II) are arranged at a distance (A) in relation to each other, irrespective of the total number of the planes of tubes, forming a continuous intermediate covering (5) running parallel to the ground side (4) of the base (1), in such a way that the smoothed down sides of the tubes (2, 3) all face the intermediate covering (5). The inventive design provides for advantageous construction parameters of the elastic base.

    摘要: A sound protection device for reducing the propagation of airborne sound comprises a track system and an elastically deformable, low sound-protecting wall made of rubber or plastic and extending in the longitudinal direction of the track. The sound-protecting wall is arranged at a distance to the track and on the side facing the track has a profile which essentially extends across the entire height of the wall. The side of the protecting wall facing away from the track has a generally even surface. The inner side is inclined at an angle a and the outer side at an angle .beta. to the track, whereby angle .beta. is greater than angle .alpha.. The profile of the inner side consists of a system of lips, which lips points towards the floor of the track at an angle .gamma.. The top of the low sound-protecting wall ends in a lip inclined towards the track, which lip points upwardly at an angle .delta.. In addition, the low sound-protecting wall comprises at least one hollow chamber extending in the longitudinal direction of the track.
