바닥슬래브 하부 구조의 개선을 통한차음특성 변화에 관한 실험적 연구 - 흡.차음재를 중심으로 -

The aim of this study is to suggest a fundamental data to improve the sound insulation performance of floor. To achieve the aim of this study, 8 types of sound-absorbing and sound insulation materials were installed under the slab, and the floor systems were compared to the general floor system which was composed of slab, timber frame, gypsum board and wallpaper.
