摘　　要：混响室是声学专业的实验室用房,它在测量声波无规入射时材料的吸声系数和测量噪声源的声功率级中得到了广泛应用。结合混响室建设的工程实例,介绍了混响室设计中有关体积、体形、吸声、隔声和声扩散等方面的技术问题。测量表明,建成完工后的混响室在声学方面的各项指标均满足或优于国家标准的要求。Reverberation room is the special test room that is used in acoustics. In the measurement of sound absorption coefficient in random incidence and determination of sound power levels of noise sources, the reverberation room is used very extensively. Combined with the project of reverberation room, some technical problems such as the volume, type, sound absorption, sound insulation and sound diffusion are introduced. After the reverberation room is built, it is showed by acoustical measurement that every index is satisfing or better than of the national standard.
