Claim:
1. A noise protection wall for traffic routes comprising: a sound protection component, said sound protection component comprising an absorber element arranged in a self-supporting manner, said absorber element being constructed as a porous absorber and provided with a substantially corrosion-proof reinforcement comprising metal arranged in the absorber element, said reinforcement being constructed as an at least two-dimensional supporting structure; and a plate-shaped reflection element having opposing parallel surfaces and being embedded in the absorber element and constructed different from the reinforcement, said plate-shaped reflection element predetermining acoustic properties of the sound protection component and insignificantly contributing to mechanical properties of the absorber element, wherein a surface normal of the parallel surfaces of the plate-shaped reflection element is parallel to a thickness direction of the absorber element, wherein the material of the absorber element is a bulk-porous concrete.
