Definitions
- the invention relates to a soundproofing device for reducing airborne sound propagation, comprising a track system and an elastically deformable low-soundproofing wall made of rubber or plastic that runs in the longitudinal direction of the track, wherein the low-soundproofing wall arranged at a distance from the track has a profiling on its side facing the track (inside). which extends essentially over the entire wall height, while its side facing away from the track (outside) is mostly flat (DE-A-44 34 269).
- the soundproofing walls move closer to the tracks and thus to the clearance profile or protrude into the clearance profile.
- a soundproof wall has to meet two different requirements.
- the soundproofing wall as a sound shield, should interrupt the line of sight from the emission location to the immission location and enable the highest possible diffraction edge.
- the airborne sound impinging on the side of the emission location should be absorbed as effectively as possible or reflected in such a way that the airborne sound is otherwise absorbed.
- a low-noise barrier should now be provided, which is designed in such a way that no car material is damaged in the event of collisions. Furthermore, its function should not be significantly reduced even in the event of minor damage to the low-noise barrier.
- the low noise barrier has at least one cavity running in the longitudinal direction of the track.
- the inside 6 of the low-noise barrier 5 has an angle of inclination ⁇ of in particular 5 to 10 °, in relation to the track perpendicular X. In addition, it is closed at the top by a lip 9 inclined towards the track 1, which points upwards, the angle of inclination ⁇ is in particular 30 to 45 °, also based on the track perpendicular X.
- the angle constellations according to and ⁇ reflect the airborne sound emitted by the wheel and rail in an optimal manner to the track floor 4.
- the inside 6 of the low-noise protection wall 5 is also provided with a plurality of lips 8, which face the track floor 4, the angle of inclination ⁇ being in particular 40 to 60 °, specifically with respect to the track horizontal Y.
- This lip system primarily absorbs the high-frequency airborne sound, by repeatedly reflecting the airborne sound in the area of the lips 8.
- These lips advantageously have a minimum length in the direction of extension of 5 mm, in particular a length of 10 to 20 mm.
- the lip 9 pointing upwards and closing the low-noise protection wall 5 is longer than the lips 8 pointing towards the track floor 4.
- the height H of the low-noise barrier 5 is expediently 300 to 700 mm.
- the cavities 10 contained in the low-noise protection wall 5 and extending in the longitudinal direction of the track act as cavity resonators, in particular to absorb low-frequency airborne noise.
- the cavities advantageously have different volumes.
- the fastening 11 of the low-noise protection wall 5 takes place approximately at the height of the rail fastening 3, preferably in the area of the threshold edge.
- the lips 8 on the inside 6 of the low-noise protection wall 5 are covered with an insulation mat 12, the insulation mat preferably being made of a foamed or fibrous material, which leads to a further reduction in the airborne sound propagation.
