摘要：以小空间的室内声场为研究对象，针对两个同等规模的小空间分别采用ODEON和CARA CAD对其声场进行设计和模拟，然后根据声场设计方案和仿真结果对两个小空间实施声学装修，再分别对两个小空间的声场进行检测和分析。通过小空间的音质设计和实践来阐述基于ODEON及CARA两种声场设计软件设计的效果及特点。最后从声学设计的正确性、合理性、实施性三个方面对声场设计指标进行验证和分析，对这两种软件在小空间声场设计中的表现给出了评价和建议。%The indoor acoustic field of a small room is studied. The other two small rooms of the same size are taken as reference rooms, and ODEON code and CARA CAD code are used to design and simulate the sound fields of the two rooms. Afterwards, the two rooms are decorated according to the sound field design and simulation results. Then, the sound fields of the two rooms are tested and analyzed respectively. Through the sound quality design and practice in the two small rooms, the effect and characteristics of the two codes, ODEON and CARA, for sound field design are expounded. Finally, the correctness, rationality and feasibility of the sound field design are verified by analyzing the results, and the evaluation and suggestion of the two codes, ODEON and CARA, used in the design of small rooms are given.
