In this paper, we experimented on a numerical experiment and a real large floor to show the vibration propagation characteristic of the dry double floorings which depended on the impulsive force. In the numerical experiment, it was confirmed that the eifference of the shape of the impulsive force was one of causes of the difference by nonlinear. In the real large floor experiment, it was different that the propagation characteristic measured by impulsive force characteristic (1) and (2) (JIS A 1418-2:2000). The attenuation of the vibration of impulsive force characteristic (1) was small in 80-500Hz (1/3 Oct).
