An interlayer noise control member is provided to minimize noise, to improve adiabatic effect, to cut down on energy, to increase soundproof and moisture-proof effects and to make construction simple by forming many whirling sound absorbing holes on the upper and lower surfaces of high-density expanded Styrofoam, guiding the noise generated from the upper and lower floors and removing noise in the inside. The interlayer noise control member(1) is formed by shaping high-density expanded Styrofoam in the rectangular or square shape and provided with many whirling sound absorbing holes(2) formed on the top to guide noise generated from the upper floor and the lower floor to be eliminated, grooves and projections formed on the bottom to keep a gap with a slab layer regularly, a thin-film type auxiliary sound absorbing member placed on the lower part of the projections to form a space containing projections and grooves to eliminate noise more smoothly. |
