摘要
Abstract
Reverberation time is an important parameter in building acoustics design and sound quality evaluation. In the classical theory of architectural acoustics, reverberation time of a hall relates to its cubage, total inner surface area and average absorption coefficient. When calculating or simulating reverberation time of theatre auditorium, the proscenium arch is treated as an important sound absorptive plan which is attached with an experiential absorption coefficient. But in practical situation this experiential absorption is not exact. This article simulates the models of the same theatre with and without stage space, and researches the absorption situation of proscenium arch under different acoustics situation of auditorium and stage at the premise of the same reverberation time in auditorium.关键词
