本文介绍了作者在哈尔滨设计建造的冰质天坛回音建筑的声学现象，通过测试、计算和分析表明，冰质天坛回音建筑再现了北京天坛回音壁内的声学现象，从而验证了项目组关于天坛声学现象机理分析的科学性，为天坛的科学保护和合理利用提供了可靠的科学依据。
This article describes the acoustics of the ice-quality Tiantan echo building that the author designed and built in Harbin. Through tests, calculations and analysis, it was shown that the echo of the ice-quality Tiantan echoes the acoustics in the whispering wall of the Beijing Temple of Heaven, thus validating the project team’s acoustics on the Tiantan. The scientific nature of the phenomenon mechanism analysis provides a reliable scientific basis for the scientific protection and rational use of the Temple of Heaven.
