Claim 7:
8. A sound insulation structure for a building, comprising:
a floor material;
a ceiling material opposed to the floor material in a vertical direction with a space in a building interposed therebetween, the ceiling material being made of a gypsum plasterboard;
a partition wall extending in the vertical direction, partitioning the space into a first space and a second space adjacent to each other in a horizontal direction, and having a first outer surface facing a first space side and a second outer surface facing a second space side; and
at least one face material out of a first ceiling-side sound insulation face material having a coincidence frequency different from that of the ceiling material, stuck to at least a portion of the ceiling material between a position corresponding to the first outer surface and a position corresponding to a center of the first space in the horizontal direction, being made of a gypsum plasterboard, and having a thickness different from that of the ceiling material and a second ceiling-side sound insulation face material having a coincidence frequency different from that of the ceiling material, stuck to at least a portion of the ceiling material between a position corresponding to the second outer surface and a position corresponding to a center of the second space in the horizontal direction, being made of a gypsum plasterboard, and having a thickness different from that of the ceiling material, wherein:
the sound insulation structure further comprises a first cradling and a second cradling adjacent to the first cradling, the first cradling and the second cradling overlapping the ceiling material in the vertical direction and disposed so as to come into contact with the ceiling material, and
the at least one face material is stuck to the ceiling material in a space between the first cradling and the second cradling.
