This study focuses on the effect of the clang sound from fittings, furniture, tableware, etc., on the perception of floor vibration caused by walking and other human motions. First, the psychological scale to measure the vibration and sound is constructed by the sensory test. Second, the physical value representing the psychological scale is introduced on the basis of the measurement of the vibration and sound. The relationship between the psychological scale and the physical value reveals that the loudness of the sound affects the perception of the vibration. Finally, the evaluation index of the perception of the vibration influenced by the clang sound is proposed.
