<p>A noise-proof element for preventing noise from being transmitted from the floor and interlayer of a building, which can block or absorb noise and shield static electricity, electromagnetic waves and water vein waves without deformation caused by changes in temperature, and a method of preventing interlayer noise using the same. The noise-proof element (10) of the current invention includes an upper plate (12); a supporting part (14) for supporting the upper plate (12); filling means (15) charged in the supporting part (14), and further includes noise-proof means (16) formed of rubber and provided on the lower surface of the supporting part (14). The supporting part (14) has a plurality of supporting legs, among which the supporting legs for supporting both sides of the upper plate (12) are longer than the other supporting legs. The upper plate (12) further includes elongated slits (18) to prevent deformation of the upper plate due to expansion and contraction of the upper plate caused by changes in temperature. According to the current invention, first, the noise-proof element may function to effectively prevent noise from being transmitted from the floor and interlayer of a building and to prevent moisture from condensing on the floor. Second, deformation of the noise-proof element due to expansion and contraction thereof caused by changes in temperature may be prevented. Third, electromagnetic waves and water vein waves may be shielded from being transmitted from the interlayer of a building.</p> |
