中国四大回音建筑之一——四川石琴的频谱分析

四川石琴和天坛回音壁、山西莺莺塔，以及河南蛤蟆塔一起被称为我国“四大回音建筑”。它们以其奇妙的回音现象成为我国宝贵的文化遗产，在世界建筑史、物理学史、声学史上亦属罕见，成为人类建筑艺术上不可多得的瑰宝。１９９０年８月、１９９３年６月，作者两次亲赴现象，对四川石琴声学现象及其历史进行考察，利用先进的测试分析仪器，运用物理学和声学的基本原理，对四川石琴进行了实验测试，通过对其回声的波形、频谱进行分析，

ONE OF THE FOUR FAMOUS ECHO ARCHITECTURES IN CHINA: SPECTRAL ANALYSIS OF THE SICHUAN STONE LUTE

The Stone Lute in Tongnan County of Sichuan, the Temple of Heaven in Beijing, the Ying Ying Pagoda in Yongji County of Shanxi, and the Hama (Frog) Pagoda in Sanmenxia City in Henan are regarded as China's four famous ancient echo architectures. Their magical acoustic phenomena are rarely found in the history of ancient buildings and physics of the world, and they have become art treasures in architectures. The authors have been to Sichuan twice to observe and study the acoustic phenomena and histories of the stone lute in August 1990 and May 1993. Using modern equipment and based on the principle of physics and acoustics, they tested the stone lute and analyzed the wavy curve and frequency of its echo and discovered the forming mechanism of the Sichuan stone lute. With this a reliable basis for protecting and making good use of stone lute are supplied. This new discovery and its scientific explanation are very important for exploiting the resources of tourism of Tongnan and promoting its development.
