Abstract (en)
[origin: EP2157242A2] The cassette has an open or closed box profile (4), whose ends are fastened in acoustic barrier wall. A damming body is arranged inside the box profile. The box profile is partially filled with a hardenable casting compound (5) i.e. splint concrete, that is formed from a sound-absorbing filling material. The hardenable casting compound is made on basis of a polymer mass, polymer foam, or polymer-bound casting compound. The box profile is made of metal e.g. aluminum plate, or plastic e.g. fiber-reinforced polymer (GRP), or wood.
