本文分析了大型厅堂混响时间计算值与实测结果的差异,指出了产生这种差异的主要原因是在于天棚的透声。当天棚采用了轻质材料时,这种差异颇为明显,特别是在低频方面尤其显著。混响室的设计者往往忽略了吸声材料的透声问题。为了解决上述问题,文中提出了新的混响室设计的建议。 This paper analyzes the differences between the calculated and measured results of the reverberation time in a large hall, and points out that the main reason for this difference lies in the transparency of the ceiling. When light weight materials were used in the shed, this difference was quite obvious, especially at low frequencies. Designers of reverberation rooms often ignore the sound transmission problem of sound-absorbing materials. In order to solve the above problems, the new reverberation room design proposal is proposed in the article.
