为了满足剧场类建筑的功能性和舒适性要求，需在建筑内布置复杂的空调系统和设备，这些设备的运行和建筑的外环境均造成了场内广泛的噪声源，因此，对空调系统内设备的噪声防治就成为保证剧场声学效果的关键。目前，国内外的文献对剧场内空调系统的降噪措施、测试方法及测试数据缺乏详细的资料。本文以上海交响乐团迁建工程为研究背景，详细介绍了该项目机电安装工程中各项空调系统降噪措施的实施，通过实际测试得出了排演厅各测点的噪声均为20dB左右，符合甲等剧院的要求。本文介绍的降噪措施及测试方法希望能对今后类似机电安装工程的实施提供参考。

To meet the requirement of function and comfort to the theater, many air condition systems and equipment should be arranged into the building. The operation of the equipment and noise of surrounding out of building caused a large origin of noise to theater. Therefore, prevention of noise to air condition systems was a key to commit the effect of acoustics for theater. There was lack of references in reducing technology, testing method and data to noise of air condition in both internal and abroad currently. This paper referred the relocation of Shanghai symphony orchestra project as research background, introduced the methods of noise reducing in air condition system during the electromechanical installation progress. The test showed that the noise of every station in rehearsal room was lower than 20dB and managed the standard of graded A theater. The methods of reducing and testing the noise afforded the reference to the similar electromechanical installation project.
