Purpose: Researching flooring materials that use rubber dampers to disperse impact on the floor and reduce slab vibrations, thereby minimizing noise. Method: The characteristics of the currently used floating floor structure and cushioning materials will be analyzed to assess their impact on reducing heavy impact noise. Next, the physical and mechanical properties of rubber cushioning will be examined to evaluate its suitability for reducing heavy impact noise. Various conditions will be considered to design a floor structure that incorporates rubber cushioning, and its noise reduction effectiveness will be experimentally verified. To achieve this, a simulated floor structure will be constructed in a laboratory setting, and the experimental results will be analyzed to evaluate the noise reduction effect of rubber cushioning. Optimal design solutions for a floor structure utilizing rubber cushioning will be derived from this analysis. Result: The potential for reducing heavy impact noise by 8dB through the installation of floor dampers in an anti-vibration structure was suggested. Conclusion: The level of inter-floor noise varies significantly depending on numerous factors, making it essential to conduct noise tests in certified locations. Testing a wide range of materials with applied vibration-damping materials is increasingly necessary to validate the effectiveness of reducing heavy impact noise.
연구목적: 고무완충재를 활용하여 바닥충격을 분산시키고 슬래브 진동을 저감하는 원리를 통해 소음을 줄일 수 있는 바닥 재료를 연구하고자 한다. 연구방법: 현재 사용되고 있는 뜬 바닥구조와 완충재의 특성을 분석하여 중량충격음 저감에 미치는 영향을 평가할 것이다. 이후 고무완충재의 물리적, 기계적 특성을 조사하고, 중량충격음 저감에 적합한 재료인지 평가할 것이다. 다양한 조건에서 고무완충재를 적용한 바닥구조를 설계하고, 중량충격음 저감 효과를 실험적으로 검증할 계획이다. 이를 위해 실험실 환경에서 모의 바닥구조를 구축하고, 실험 결과를 분석하여 고무완충재의 중량충격음 저감 효과를 평가하고, 고무완충재를 활용한 바닥구조의 최적 설계 방안을 도출할 것이다. 연구결과: 방진구조로 바닥완충재 설치 시 중량충격음을 8㏈ 저감하는 가능성을 제시하였다. 결론: 층간소음은 다양한 변수에 따라 소음측정 결과 값 정도가 바뀐다. 시험의 장소가 공인된 장소로 하고 방진자재가 적용된 자재를 많이 시험하여 중량충격음 저감에 대한 효과 검증이 더욱더 요구된다.
