요약2 Bang machines and rubber balls, which are currently used as heavy-weight impact sources for floor impact sound measurement, have characteristics that differ from the actual impact patterns of children. This is because the current impact source is larger than the actual impact force of the child, and there is a single impact pattern, so a child's continuous impact is not reproduced. This study develops a trial product that can simulate and reproduce a child's running motion. It is necessary to develop an impact source that can reproduce the actual running pattern of children because it is an important factor in the development of floor structures and resilient layers corresponding to the characteristics of real impact sources. In addition, a device that can consistently reproduce a child's running pattern can be used to evaluate the performance of children's indoor shoes and floor finish materials to reduce floor impact sounds; it is expected to be useful when demonstrating children's running motions. This paper presents the manufacturing progress of the proposed prototype, and the floor impact sound characteristics of the prototype are compared with an actual child's running pattern using laboratory experiments. The results showed that the trial product was consistent in terms of reproducing the floor impact sound, and the impact sound spectrum characteristics were similar to those of an actual child, so it can be used as a floor impact source.
