项目摘要

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.

在住宅楼中产生的声音中，尤其受到抱怨的是脚步声，即行走、快步。但由于噪音存在个体差异，且重复性低，很难判断是地板系统隔音效果差、冲击力激发过大、接收器过于灵敏等因素。因此，我们通过实验制作了模拟一般人类脚步的自动冲击源，以应用于穿过地板的各种问题。在本研究中，我们研究了人类脚步的冲击力特征，考虑了规格，并根据人类脚步的调整改进了模拟器的部件。因此，模拟器产生的撞击声音可以与特定地板覆盖物和有限频率范围内的人类脚步噪音相对应。
