Their sounds may show individual walking characteristics. So we can recognize someone coming and one's physical or psychological condition by the time history pattern of their sound pressures. Their sounds are different by walking style, and there are two strong sound pressure waves at one step. The first one is a wave at heel touching down the ground and the second one is a wave at the front part of shoes getting down the ground. We study on the source of the shoes sound. The vibration generates by a collision of the shoes sole and floor, and transfers to the shoes skin. The sound radiates from the shoes skin parts. And, it is investigated that the shoes sound includes air compressing sound. Using their patterns and frequency characteristics of the sound pressures, we can understand who comes up and what is one's condition.
