| Summary: | Based on the relative lack of research on the acoustic characteristics of traditional Gan opera theaters, this paper takes the Zhaomutang theater in Leping, Jiangxi Province, as a case study. By employing impulse response measurements and sound quality index evaluation, this work investigates and analyzes the sound field characteristics of the stage, front patio, Xiangtang, rear patio, and Qintang through field measurements. The results show that the small volume and low ceiling in the stage area lead to higher early reflections and enhanced self-auditory support for performers. The semi-enclosed Xiangtang space exhibits the best speech definition and music clarity. Although the front and rear patios are open-air, they still maintain moderate reverberation and sound energy intensity due to reflections from surrounding surfaces. In contrast, the Qintang has a relatively weak early sound energy because of its volume and functional constraints. Still, its overall reverberation time is not significantly different from that in the other areas. Comprehensive indices indicate that the Zhaomutang theater balances speech intelligibility and musical richness for multifunctional scenarios—ancestor worship, opera performances, and gatherings—thus providing an enhanced viewing experience. These findings offer critical reference points for the protection, restoration, and acoustic optimization of Gan Opera ancestral temple theaters and provide an empirical foundation for further investigation into the multi-space coupling characteristics of traditional theaters. |
