Abstract
A noise control device for tracks (1) comprising sound-absorbing slabs (3) mounted at the rails (2) of the track (1), the slabs being supported on the rails (2) via elastic sections (5) and self-supportingly bridging the space between the rails (2). To improve silencing of the slabs (3) it is provided for the slabs (3) to be comprised of particles (9) of porous lightweight building material, which are combined by a binder. The slabs (3) have an embedded reinforcement (11). Advantageously, also silencing cavity resonators (14) are formed in the slabs (3). A special embodiment provides for the space between the rails (2) of a track to be bridged by slab parts (3a, 3b) arranged in pairs which are supported on each other at their rims (26, 27) facing each other.
Claims28
A noise control device for tracks comprising sound absorbing slabs mounted at the rails of the track, the slabs being supported on the rails via elastic sections, and the slabs arranged between the rails self-supportingly bridging the space between the rails, characterized in that the slabs (3;
