The purpose of this research is to estimate the characteristics of the installed resonance according to the sectional specification of the floor finishing material. First of all, as a fundamental study for that purpose, in this report, we focused on the difference in level between the floor finish material and the floor structure surface, including the investigation of resonance by installing the vibration pickup. The items to be investigated are vibration source, floor structure, etc. As a result, the increase / decrease amount of the floor finish material and the floor structure surface was clarified for each study item.
