It is the underlying object of the present invention to provide a component for effective soundproofing, in particular for sound absorption of the noise generated by rail vehicles.
This object is solved by a component having the features of claim 1, by a soundproofing wall having the features of claim 14 and by a travel path having the features of claim 18. Methods of manufacturing a corresponding component having the features of claims 19 and 20 are furthermore taught.
The component in accordance with the invention has a frame of plastic or comprises such a frame, with the frame comprising a single wall or multi-wall plastic composite. Such a component in particular serves the sound absorption of the noise coming from rail vehicles. However, the invention is not limited to such a use, but can also be used for soundproofing in other cases such as on highways.
The frame-shaped structure or the component can have one or more concavely curved walls, with preferably at least the wall directed toward the sound source having a concave shape. It is furthermore conceivable that the frame-shaped structure has at least two oppositely disposed concavely curved walls which are, for example, in specular symmetry with one another.
Such components or soundproofing elements are known in numerous different embodiments, for example on highways or railroad lines. They are used to quieten noise coming from a point-shaped or linear or areal source of noise (e.g.
roads, railroad tracks) so that the noise can be attenuated so much at an immission site to be protected (e.g. residential districts, hospitals) that the pollution is reduced and the statutory limits are observed.
It is the underlying object of the present invention to provide a component for effective soundproofing, in particular for sound absorption of the noise generated by rail vehicles.
This object is solved by a component having the features of claim 1, by a soundproofing wall having the features of claim 14 and by a travel path having the features of claim 18. Methods of manufacturing a corresponding component having the features of claims 19 and 20 are furthermore taught.
