An experimental study on the field sound insulation performance of the light weight concrete panel using bottom ash

저회를 이용한 경량패널의 현장 차음성능에 관한 실험 연구

Recently, the method of the apartment building design is changing from wall type to moment structure. Because of this reason, dry wall systems are used plentifully. This study examines the sound insulation performance of the light weight concrete panel using bottom ash. There is the difference of airborne sound isolation between laboratory and field test. For the purpose of searching deviation, we use the prediction tool(Insul 6.0). First, we calculated the prediction data and measured the sound isolation in the wall at the lab. Then, we measured it in the field and compared them. At the base of these datum, we measured the difference.
