In this study we examined how to improve performance in insulation of floor impact sound of directly glued wood flooring while taking walking feeling into consideration, and carried out sensation experiments oh walking feeling. The following are the main conclusions of the study. (1) We succeeded in development of wood flooring materials of a double-layer construction in section, that is, the upper construction (finishing material + cushion material) to reduce exciting force and the lower construction (plywood + cushion material) consisting of a rather thick plywood layer to improve the performance in insulation of lightweight floor impact sound, thus maintaining the floor hardness for walking. (2) It has been proved that for the floor elasticity for a man to walk dynamic values much correspond with sensation quantity than static ones do. The walking feeling given the highest evaluation was a flooring having a dynamic displacement of 0.6 〜 1.0mm to the local excitation by the heavyweight impact source having a peak impact force 1000N with duration of 22ms.
