카고메 트러스 패널을 활용한 벽체의 차음성능 특성 = Sound Isolation Characteristic of Wall System Using Kagome Truss Panel

다국어 초록 (Multilingual Abstract)

This study investigated the sound isolation characteristic of wall system using the Kagome truss panel through sample and full-scale sound isolation experiments. Samples (1×1 m 2 , depth:100 mm) of Kagome truss panel were first tested in the rectangular chamber. The samples consisted of various surface materials (steel plate, CRC board, gypsum board, and plywood), Kagome truss and filling materials (urethane foam, aerated concrete and light-weight concrete). Results of sample test showed that the Kagome truss panel with steel plate and urethane foam had best sound isolation performance (48 dB in Rw). Additional sound isolation experiment with wall panel (3.9×2.4 m 2 , depth: 270 mm) in full-scale was conducted in the reverberation chamber.
The wall system was comprised of gypsum board, air-space, C-stud with glass wool and the Kagome truss panel with steel plate and urethane foam, which was used in the sample test. It was shown that sound isolation performance of the triple wall system using the Kagome truss panel was 58 dB in Rw. The sole Kagome truss panel showed sound isolation performance of 44 dB in Rw, which is lower than result in sample test. It was also shown that sound isolation performance was increased by about 5 dB in Rw after installing gypsum board and glass wool, respectively. Computational analysis of sound transmission for the wall system was also conducted and compared with the results of experiment.
