바닥충격음 실험동 개요 및 성능평가

Most of floor impact sound evaluation was performed at the filed, which installed Mock-up room. This field test has limitations which is construction time, a space and install various floor structure in Mock-up room. In order to solve the limitations, we construct building for evaluation of floor impact sound. This paper introduce the design method and performance evaluation of floor impact sound in building. The design method of floor impact sound test building is on the base of the apartment building design method. The floor impact sound test building have 10 unit labs. Unit lab have 4500㎜×5100㎜×2850㎜ space size and four different kinds floor slab thickness which is l50㎜, 180㎜, 210㎜, 240㎜.
