策はなかった。2. Description of the Related Art In recent years, floor impact noise from the upper floor has become a serious problem in apartment houses and the like. There are two types of floor impact sounds: a floor impact sound caused by a light impact that occurs when walking normally, and a floor impact sound caused by a heavy impact caused when a heavy object is dropped or a child jumps. There was no effective solution other than thickening the floor slab.
