According to the regulation of exterior noise level for apartment, outdoor noise limited to 65㏈(A) among 1st floor and 5th floor. Indoor noise should be lower than 45㏈(A) for unit higher than 5th floor, if the exterior noise level exceed 65㏈(A). It is very difficult for the apartments under heavy traffic load to satisfy the regulation. And Units under 5th floor will be put under the worse noise condition comparing with units over 6th floor, because they don't need to content with the indoor noise level. Outdoor noise level for indoor for units among 1st and 5th floor is evaluated by arithmetic mean value, so whenever they met the minimum performance standard, some of them could be exposed to the noise level above the criteria. If units lower than 5th floor were designed differently from units higher than 6th floor in the planning step, they can be put over 45㏈(A). Therefore the current regulation needs to be improved to be a reasonable level

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.

Government made a regulation to protect outdoor noise from roads and railways in residential housings. Many residents are living in high rise apartments, but they complain of the noisy environment. So, high sound insulation window systems are needed against outdoor noise levels. We measured sound insulation performance of 20 windows systems in acoustic laboratory and field, and investigated the defect of sound leakage and differences of test result. On the basis of the result, it is thought to be established the guidelines for selecting the proper window system to be satisfied with acceptable indoor noise levels.
