摘要
The invention relates to a device for damping mechanical vibrations of heavy sound sources, said vibrations being sonic frequencies propagated in undesirable directions. The sound sources are placed onto the floor covering using legs and/or underlays which are arranged in the lower parts of said sound waves. The invention is characterised in that at least one layer (4) which is produced by a non-elastic material that badly conducts sound, preferably lead and at least one polyurethane layer (5), are placed between the lower parts of the sound sources and the floor covering. The polyurethane layer (5) is suitable for sound damping and is provided with a cell structure consisting of cells that are partly or entirely open. The layers are arranged in such a way that the layer (4) consisting of the non-elastic material is always closer to the sound source and that the various layers (4, 5) are arranged alternately when there are more than two layers (4, 5).
