Characteristics of a Cave-Style Traditional Stage in Shanxi Province, China
Chinese traditional stages are unique in the history of the world's ancient theaters, so they have significant meaning in research on their acoustical characteristics. Among the many Chinese traditional stages, the cave-style stages and splay walls in Shanxi Province have special acoustic effects, which are simulated using a finite-difference time-domain approach in this paper. The conformal technique combined with perfectly matched layers is introduced into finite-difference time-domain equations for sound waves, which solves the acoustic problem of a curved boundary in open space. To verify the validity of the finite-difference time-domain model, simulated values are compared with measured values. Furthermore, the sound pressure distribution of several cave-style stage models and splay walls are simulated. According to the impulse responses, several room acoustical parameters, such as loudness, clarity and reverberation time, are analyzed. Moreover, a listening test based on a paired comparison method is conducted.
