中文摘要:
      磁县天子冢和天元山景区出现两处水滴声台阶。为更好地保护和开发现存水滴声台阶声景观,研究水滴声的形成规律,采用脉冲响应方法测量了撞击声在磁县天子冢和天元山景区水滴声台阶上的频谱和声压时域特征,分析其变化规律和相关因素影响。实验结果表明,台阶对撞击声频谱有筛选作用,使其变成以某一频段为主导的特征频谱,天子冢台阶水滴声的中心频率为500 Hz,天元山台阶水滴声的中心频率为400 Hz。提出了水滴声台阶保护和设计的建议。
英文摘要:
      There are two water-drop-sound steps in Emperor Tomb and Tianyuan Mountain which are located in Cixian, China. In order to protect and develop the soundscape of water drop sound and to study the mechanism of water drop sound formation, the changes of the sound pressure and frequency spectrum of impact sound are measured by using impulse response method. The experimental results show that the steps can screen out the impact sound spectrum and transform it into a characteristic frequency spectrum dominated by a certain frequency band. The center frequency of the water drop sound on Emperor Tomb steps is 500 Hz and the one on Tianyuan Mountain steps is 400 Hz. Finally, suggestions for the protection and design of water-drop-sound steps are put forward.
