This paper presents the method to apply excitation and perception apparatus to floors covered with finishing materials. The apparatus had been developed by the author for evaluating floor vibrations caused by human walking. At first, vertical loads applied to floors by walking people and the apparatus, and floor vibrations caused by walking, were measured and compared by using some finishing materials. Secondly, from the result of the measurement and the comparison, it has been shown that the vibrations were hardly influenced by finishing materials. As a result, the method of measuring floor vibrations directly after removing finishing materials from floors, was established for the measurement method of vibrations of floors covered with finishing materials.
