In regard to the concrete slab skeleton, the method of prediction for floor impact sound level has been established from the analysis results of vibration responses focussing on impedance, which is widely utilized at the present time. In this paper, in regard to residential floor finish structure, we describe the results of the experiment on dynamic displacement and dynamic spring coefficients by using a footstep impact simulator, on impact duration by using a tapping hammer, on point impedance by using an impulse hammer and on reduction of floor impact sound level, in order to classify the floor finish structure from the vibration response characteristics and to establish the method of prediction of the reduction by using the relationship between vibration response characteristics and floor impact sound insulation performance.
