摘要: 摘 要:参考山西超山庙窑洞式古戏台的体型、结构和体积,构建了五种古戏台计算模型.模型的计算空间为14.42 m×15.68 m×5.88 m.考虑古戏台墙体材料,模型边界由刚性边界和PML完全吸收边界构成.利用时域有限差分法,通过MATLAB编程,计算了所构建的五种古戏台模型中几个不同受声点的脉冲响应,进而进行了频域分析。结果显示,窑洞式古戏台增加了声音的清晰度、饱满度、混响感等,还对部分频率的声音起到了一定的扩声作用.

Abstract: Abstract: Referring to the figure, structure and volume of a cave-style ancient stage among the Chaoshan Temple in Shanxi, five ancient stage models have been built. The computation space is 14.42m×15.68m×5.88m. Considering the wall's materials in the ancient stage, the models' boundary consists of rigid boundary and PML absorbing boundary conditions. Through the Finite-difference Time-domain method by using the MATLAB software, impulse responses of the receiving points in the five models have been calculated, which have been in spectral analysis. The results show that cave-style ancient stages can strengthen the sound's definition, satiety and sense of reverberation and so on, which can amplify sounds at some frequencies.

Key words: cave dwelling, stages, finite-difference time-domain method, impulse response, spectral analysis
