A Study on the Insulation Performance of Impact Sound Level by Striking Location of Floor Slab

바닥 슬라브의 가진 위치에 따른 차음성능에 관한 연구

This paper is contents about method to measure interception performance of shock noise of floor slab of apartment house to be simple. In the case of interception performance of light floor impact sound level, according to measurement method, grade of sound insulation performance showed greatly differently. But, in the case of interception performance of heavy floor impact sound level, it was similar result in all measurement method. Therefore, use of simple method of measurement was examined by possible fact in case of interception performance of heavy floor impact sound level.
