Effect of Sound Damping Sheet on Sound Transmission Loss in Building Structure
건축 구조물에의 차음시트 적용
Abstract
This paper deals experimentally with the effect of the sound-damping sheet on building wall system; brick wall, light wall panel, and gypsum board. Experimental results show that when the sound-damping sheet is attached on wall systems, the mass and/or damping effects result in increasing of STL of wall system depending on the characteristics of the original partition. It is pointed out that the performances of sound damping sheets must be presented with specific wall structures that applied, not by the sound transmission loss of the sheet itself.
