조적조 벽체 구성에 따른 차음성능 현황

The purpose of this study is to analyze the sound insulation performance of the masonry wall. Concrete or masonry wall has a high insulation performance. Because of its weight. If it can not handle the gaps, the sound insulation performance is degraded. If the gaps between bricks are handled poorly, the insulation degradation has occurred in approximately 12dB. The importance of the treatment gap is increased.
