Abstract

Recently, complaints of floor noise have been growing up with the rapid increase of the residential buildings. This demands the effective floor noise isolation system. Since the construction of high-rise the residential buildings will be increased even more in future, the noise isolation is a more important technology in the market. In this study, a new floor noise isolation panel (FNIP) was designed and manufactured using waste rubbers. The noise isolation was investigated at both laboratory and field conditions. Light and heavy weight shock wave showed 52 dB and 48 dB in the field test, respectively. The new system could reduce the total floor thickness by 22~42 mm.

최근 공동주택이 증가함에 따라 층간소음문제가 증가하고 있다. 이로 인해 더 효과적인 층간소음저감 시스템이 요구되고 있다. 향후 고층빌딩이 더 많이 건설될 것이므로 이런 시스템은 시장에서 더욱 수요가 요구되어지는 중요한 기술이다. 본 연구에서는 폐고무를 이용하여 신규 바닥 소음 저감 판넬을 설계하고 제작하였다. 실험실 및 실제 필드조건에서 소음 저감을 조사하였다. Field test 결과 경량 및 중량충격음 레벨이 각각 52, 48 dB로 우수한 결과를 보였다. 기존 구조 대비하여 22~42 mm의 두께 저감을 할 수 있었다.
