 note = {Humans often recognize someone's footsteps, though the footstep sound contains many noise and partial tone components. Also, the high and low of footsteps can sometimes be recognized, which indicates the footsteps have a pitch. It may be similar to drum and percussion sound. In this paper, a pitch extraction of those percussion sounds was discussed by GHA (Generalized Harmonic Analysis) with twelve-tone equal temperament. And each pitch of the sound was subjectively evaluated by 4 subjects. In results, the pitch felt by subjects was included in frequency components extracted by the GHA.},
