To provide a double structure (a double floor structure and a double ceiling structure) efficiently reducing the impulsive sound of a heavy floor over a wide band and easily and positively constructed without making structural load to a structure excessive.
The double floor structure 10 of the structure has a floor foundation bed 12 of the structure, a plurality of support legs 20 arranged on the floor foundation bed 12, and floor panels 13 supported facing the floor foundation bed 12 by the support legs 20. A plurality of dampers 30 each provided with a fixed layer 31 higher in Young's modulus than a viscoelastic body 32, on the surface of the viscoelastic body 32 is adhesively joined to the floor foundation bed 12, and the fixed layer 31 and the floor panel 13 are connected by screw spikes 35.
