Abstract
In this paper, shoes sounds at walking are investigated. Their sound 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 investigate what part of the sound wave shows someone's feature. We don't understand the source of generating walking sound yet. Then we investigate the source by analysis of exciting response method.
