| Research Abstract |
Footstep noises, i.e., walking, quick stepping, are in particular complained among generated sounds in residential buildings. However, it is difficult to judge the factor whether weak sound insulation of floor system, excessive impact force exciting, over sensitiveness of receiver because the noises are individual differences and low repeatability. Therefore, we produced automatic impact source simulating general human footstep experimentally, in order to apply to various problems through the floor. In this study, we conducted to investigate the characteristics of impact force by human footsteps, to consider the specifications, and to improve the parts of simulator due to adjust to human footsteps. Consequently, the impact sounds generated by the simulator could correspond with human footstep noises within specific floor coverings and limited frequency range.
