요약2 Non-load bearing walls are widely used to facilitate the redesign of multi-residential housing spaces. However, as there are different noise characteristics between load bearing walls and non-load bearing walls, the effect of implementing non-load bearing walls on floor impact noise and slab vibration compared to load bearing walls needs to be studied. In this study, field experiments are carried out in a mock-up structure with various types of light-weight dry walls to evaluate the effect of implementing non-load bearing walls on floor impact noise and slab vibration. We find that there are little differences in the slab vibration and the floor impact noises between the different types of light-weight dry walls. This study also performs a series of numerical analyses for different types of light-weight walls and load-bearing walls to evaluate the effects on slab vibration and floor impact noise. From the numerical analyses, it is observed that the types of light-weight walls makes little difference to the effect on slab vibration and floor impact noise which is consistent with the field test result. However, the numerical analyses show that the floor impact noise characteristics are different between the load-bearing walls and the light-weight walls because the effective plates are different, although the configuration of the slab is the same.
