2. Description of the Related Art In apartment houses and two-story houses such as condominiums, the floor noise problem is becoming serious. The floor noise is a squeak sound caused by friction generated between the floor boards and the joists underlying the floor boards or between the floor boards. In particular, woody materials are easily affected by humidity, and when members such as floorboards shrink due to drying, gaps are formed between the members, and floor noise is likely to occur. Therefore, conventionally, it has been attempted to prevent floor noise by applying a liquid floor noise inhibitor such as a surfactant, a liquid oil or a liquid polyethylene glycol to each member, for example, a joint portion of a floor plate material. I have. The inhibitor easily penetrates into the gaps between the members, effectively fills the gaps, suppresses friction between the members, and prevents floor noise.
