Abstract
The reduction of floor noise is important issue to improve quality of the life. The flexural vibration by heavy impact is the main cause of noise in building. The purpose of this study is to reduce the floor vibration of the building using environmentally friendly material. A damping pad composed of metal recycling materials was suggested. The properties of the pad was measured using transfer function method. The constrained layer damping analysis was used to investigate the effect of the pad on floating floor structure. The performance of the pad was estimated by the experiment in the building. The pad showed higher performance compared to the existing vibration reduction methods. The result of experiment was compared with the vibration analysis.
