공동주택의 소음 현황에 관한 실험적 연구

The noises in apartment houses are important factor that determine the quality of indoor sound environment. Particularly, floor impact noise and plumbing noise and outdoor noise has caused the uncomfortable environment in the apartment houses. So in this study, field measurements of floor impact sound and plumbing noise and outdoor noise were carried out in the apartment house. And the plans to improve the performance of indoor environment were studied. As the results of the measurements, the levels of heavy-impact floor noise and plumbing noise and outdoor noise exceeds the regulations at currently condition. The heavy-impact floor noise level were decreased 15-33dB in higher 125Hz when the floor changes the wet construction method with resilient material. And the plumbing noise and outdoor noise are also expected to decreased as the change of pipe systems and system windows.
