为改善本校文远楼大讲堂内的音质缺陷,我们曾进行了一系列的音质测定和分析工作,并作了改建设计。1956年暑改建完毕以后,基本上已能符合听讲的要求,听者一般都感到清晰和满意。由于声学仪器和实际经验的不足,工作中尚存在着一些缺点和问题,在本报告中亦一一提出,以待今后继续加以研究解决。Ⅰ.绪言。Ⅱ.现况介绍和分析。Ⅲ.从几何声学上加以分析和改进。Ⅳ.混响时间的改进。Ⅴ.改建后的声强分布。Ⅵ.降低噪声的措施。Ⅶ.工作中存在的问题和缺点。

In order to improve the sound quality defects in the Wenyuan Building auditorium of our school, we have conducted a series of sound quality measurement and analysis work, and made a remodeling design. After the completion of the summer redevelopment in 1956, it basically met the requirements for listening, and listeners generally felt clear and satisfied. Due to the lack of acoustic instruments and practical experience, there are still some shortcomings and problems in the work, which are also proposed in this report, pending further study and solution in the future. I. Introduction. II. Present situation and analysis. III. Analyze and improve from geometric acoustics. IV. Improvement of reverberation time. V. Sound intensity distribution after reconstruction. VI. Measures to reduce noise. VII. Problems and shortcomings in the work.
