PURPOSE: To diminish the impact noise of a floor exerting the downstairs by interposing underground material between floor joints and a ceiling board, which forms left and right directional spaces for communicating front and rear directional spaces defined by a floor board, ceiling board, and left and right floor joists. CONSTITUTION: The cushion material 2 of a foam vinyl sheet for impact and acoustic absorption is adhered on the surface of a plywood floor board 1. Also, floor joists 4 are joined to the rear face left and right circumferential edges of the floor board 1, and the ceiling board 5 of a plaster board is arranged in a manner being faced to the lower side of the floor board 1. Furthermore, underground materials 7 are interposed between the floor joist 4 and the ceiling board 5 at front and rear distances; thus, front and rear directional spaces 8 defined by the floor board 1, ceiling board 5, and left and right floor joist 4 are permitted to communicate with the left and right directional spaces 9 defined between the front and rear underground materials 7.
