Apartments represent the typical accommodation for over 60% of the South Korean population. However, as multiple families reside in units of the same building, conflict often arises between neighbors. In particular, floor-impact noise caused by walking or children running has become a social problem that demands alternative solutions. Impact sounds are caused by vibration transmitted through slabs or walls. In this study, an embedded resilient layer was used to reduce the transmission of vibration. The vibration of slab and walls of the specimen indicated different rates according to the frequency band. Below 100 Hz in the frequency, the slab showed large vibrations. Above 100 Hz, wall vibrations had a stronger impact. The experimental data showed that the vibrations and noises were transmitted to slabs and walls, especially heavy-weight floor-impact noises, were effectively reduced by an embedded resilient layer.
