The present invention relates to a structure for preventing interlayer noise, which is installed between a foundation bottom layer and a top finishing mortar layer in a multiple storey building, including a dust-proof panel, which has hollow protrusion units protruding from the entire surface on the top surface where the finishing mortar layer is coated and which has multiple supporting pins protruding from the bottom layer. Inside each protrusion unit of the dust-proof panel, vibration absorption liquid is filled. Also, the structure includes an insulation material panel, which is attached to the bottom surface of the dust-proof panel and has multiple supporting pins penetrating through the dust-proof panel and protruding from the bottom surface; and multiple dust-proof rubber units, which are combined with the multiple supporting pins protruding from the bottom surface of the insulation material panel and are supported by the foundation bottom layer. Therefore, provided is the structure for preventing interlayer noise, which shows excellent performance of blocking the transmission of interlayer vibrations or impacts.
