In the present paper we examine a method of presuming the impulsive impedance of wooden floor construction against heavy weight impact sounds. With wooden floor construction, vibration at the time of floor impact is often partial because of dimensional and construction problems, particularly the initial response at the time of floor impact is noticeable. Since the heavy weight floor impact sound is directly influenced by the initial response characteristics, it is necessary to presume the initial response more accurately for estimation. In this paper, an impulsive impedance is introduced as a means of grasping the initial vibration characteristics of a floor, presenting a calculation method in which a floor construction is presumed as a single vibration system composed of a beam bending spring and effective mass of the floor construction, being compared with the actually measured values obtained from the actual floor construction, thus showing the effectiveness of this method.
