Main acoustic attributes and optimal values of acoustic parameters in Peking opera theaters

Abstract

To perfect the audience's enjoyment of Peking opera performance in modern theaters, the present study set out to identify the main subjective attributes for good acoustic quality of Peking opera and find out the optimal values of correlated acoustic parameters. Firstly, the importance of the subjective attributes was evaluated through a social survey by audience in Peking opera theaters. Then, the correlated acoustic parameters were identified. Lastly, in order to obtain optimal values of the acoustic parameters, subjective preference tests were conducted and the factors influencing the preference scores were also investigated. The social survey revealed that the most valued acoustic attributes apart from the loudness were clarity and liveness of voice. The acoustic parameters correlated with the attributes were reverberation time, frequency characteristics of reverberation time and sound level. The subjective preference tests revealed the optimal value of occupied reverberation time was around 0.6 s. The optimal frequency characteristics of reverberation time was the one with more reverberation in higher frequencies. The optimal sound level for young group was 70–73 dBA. When comparing the experienced and young group, there was no significant difference in expectation in acoustic attributes. What was unique in young generation’ preference in acoustic parameters was that the optimal range of reverberation time was longer for young people (0.6–1.0 s) than it was for the experienced people (0.2–0.6 s). The present study will facilitate the construction of Peking opera theater with good acoustics and boost the revitalization of the cultural heritage.
