天坛声学现象的首次测试与综合分析

THE FIRST EXPERIMENT AND ANALYSIS OF SOME ACOUSTICAL PHENOMENA OF THE TEMPLE OF HEAVEN IN BEIJING

世界上最大的祭天建筑群──天坛，以其宝贵的艺术价值和丰富的文化内涵为举世瞩目，又以其奇妙的声学现象位列我国四大回音古建筑之首。该文首次运用现代物理实验方法和先进的测试仪器对天坛声学现象进行了现场测试与综合分析，揭示了“回音壁”、“一音石”、“二音石”、“三音石”、“圜丘台”和新发现的“对话石”声学现象机理，对古建筑声学现象研究提出了一些新见解。

The Temple of Heaven in Beijing is the world's largest architectural complex for sacrificing to Heaven. It is put in the first place of China's Four Echo Buildings for its wonderful acoustical phenomena. The result of our investigation of the acoustical phenomena of its One Sound Stone, Double Sound Stone, Triple Sound Stone and Circular Mound is recorded in this article. The authors explain these phenomena scientifically by analysing them synthetically. They also found something new in this experiment.
