신축공동주택의 상하층간 소음 및 진동전달 특성과 층간소음 차단성능에 관한 연구 = Study on the Characteristic of Floor Sound and Vibration Transfer and the Blocking Function of Floor Sound for Newly Built Apartment House

다국어 초록 (Multilingual Abstract)

This study involves 2 newly built apartment houses which are A with 23 floors as 150 mm slab width and B with 16 floors as 180 mm slab width. The impact was added by tapping and bang machine at the middle floor level of these 2 apartments and the test was arranged in terms of the characteristic of vibration and sound level which transferred to upper or down floors. As a result, impact floor shows the highest value in terms of both sound and vibration level and followed was at down floor of the Impact floor. Also, blocking function for the lightweight and heavyweight floor impact sound level was tested for each room of the apartment A and B including living room, main room, room 1 and 2. As a result, sound blocking function of B apartment was better than that of A and the function was getting worse when the room size is getting smaller.
