Considering the reduction measures for floor impact noise, it is widely known the increasing the thickness of floor slabs and a method of using a sound insulating material as a finishing material shown the improvement. In this study, a dynamic damper using asphalt damping material is proposed as another new floor impact noise reduction method. We report the change in characteristic vibration during damper adjustment and the floor impact noise reduction effect when installed on a floor in 2×4 structure as an example of damper installation.
