The interlayer noise is transmitted through the floor, the wall, or the pillars between the floor and the floor where the noise and the vibration generated during the walking or work (moving furniture, nailing, cooking, etc.) This means a disgusting sound.
Therefore, it is very important to prevent the interlayer noise for the residence stability and convenience of residents when building the building. Therefore, various technologies for removing the interlayer noise have been provided and hundreds of patents for controlling the interlayer noise have been provided.
As an example of patents for controlling the interlayer noise, Korean Patent No. 10-1407137 (Announcement of Jun. 13, 2013, Prior Patent 1), "Interlayer Noise Reduction Device", Korean Patent Publication No. 10-2013-0047714 (2)), and a device board for buffering the noise and shocks between the apartment houses 'apartment buildings of the apartment house' of the apartment building of the apartment building of the No. 10-2014-0114313 (published on September 26, 2014, 'And so on.
