A Study on the Floor Impact Sound Insulation Performance of Apartments depending on the Damping Materials

완충구조에 의한 공동주택 바닥충격음 차단성능 변화 연구

This study aims to propose fundamental data for development of noise reduction system that is applied to classification for light-weight impact sound. For this reason, eight types of damping materials were constructed in new construction field. Comparison and analysis among the reduction materials were carried out on the acoustical characteristics through test. In the end, the suitability as a damping material was evaluated by the analysis.
