摘　　要：之江实验室声学实验室包括消声室、半消声室、混响室和听音室,结合实验楼整体布局,确定了声学实验室内部结构尺寸,提出了声学设计性能要求,为类似声学实验室的设计和规划提供参考。建成后,按照JJF 1147、JJF 1143和GB/T6881.1-2002分别对消声室、半消声室、混响室和听音室声学性能进行了测试,结果表明,该声学实验室达到了预期设计目标,可提供高精度的声学环境,为之江实验室开展相应的声学研究提供了基础环境条件支撑。An acoustic laboratory of the Zhijiang Laboratory includes an anechoic room, a semi-anechoic room, a reverberation room and a listening room. Based on the overall layout of the experiment building, the internal structural dimensions of the acoustic laboratory were determined, and the acoustic performance design requirements were put forward,which can be used in the design and planning of similar acoustic laboratories. After the construction, the acoustic performance of the anechoic chamber, the semi-anechoic chamber, the reverberation chamber and the listening chamber was tested respectively according to national calibration specifications JJF 1147 and JJF 1143. The results show that the acoustic laboratory has achieved the expected specifications and it can provide a high-precision acoustic environment for acoustic research in the Zhijiang Laboratory.
