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。

Abstract:

Abstract: This article is based on indoor acoustic field of small room as the research object. According to two of the same size small rooms, we use ODEON and CARA CAD to design and simulate the sound field. After that we decorate the two rooms according to sound field design and simulation results. When the decoration finished we test and analyse the sound field of the two rooms respectively. The whole text aims at expounding the effect and characteristic of ODEON and CARA by the sound quality design and practice in two small rooms. Finally, we verify and analyse the rusults of sound field design from the correctness ,rationality and operability. In the end, the evaluation and suggestion of ODEON and CARA used in design of small rooms are given.
