A Study on the Reduction of Floor Impact Sound according to the Thickness and Stiffness of Slab

슬래브 두께 및 강도의 변화에 따른 바닥 충격음 특성에 관한 연구

This study was carried out in the laboratory of the reverberation. A total of six specimens were fabricated depending on the thickness and strength. Floor impact sound insulation performance was measured in 1/3 octave band center frequency. The results of this study are as follows. Although some differences in the frequency band, the result of evaluating the weight impact sound blocking performance as the thickness increases, the floor impact sound insulation performance is improved. In addition, to increase the strength of the slab, even if the block impact sound performance is improved.
