Immersed in the rich tapestry of traditional culture, Gugak, the traditional Korean music stands as a captivating embodiment of artistic expression. This study embarked on a comprehensive evaluation of a Gugak hall, employing acoustic measurements, computer simulations, and subjective perception surveys. The evaluation focused on the reverberance, clarity, spatial impression, and preference, unravelling the secrets that shape the immersive Gugak experience. Through intricate computer simulations and auralization, the experience of Gugak performances was meticulously brought to life, allowing exploration under diverse conditions by adjusting stage volume ratios from −20% to +20% and modifying the interior materials, including the walls, ceiling, and lateral reflectors. Although Gugak halls exhibited relatively low values of reverberation time (RT), early decay time (EDT), and binaural quality index (BQI) the dominant factor influencing the acoustic environment was the effect of sound strength (G). Musical clarity (C80) value did not show an inverse proportionality to the reverberation time. Furthermore, genre differences between traditional Korean and Western classical music did not significantly affect listeners’ perception and satisfaction with regards to reverberance, clarity, and spatial impression. As a result, Gugak halls can adhere to the same acoustic design criteria as Western orchestra halls, since this study found that people perceived them the same way. In this study, sound strength was found to be strongly correlated with perception indicators. It was possible to enhance listeners’ perception and preference regarding the acoustic environment through material and structural changes to the sidewalls and ceiling. These changes improved the reinforcement of low frequencies and simultaneously enhanced the relative effect of side reflections. Additionally, enhancing the reflection and spatial characteristics of the materials effectively improved listener preference. Based on these findings, an optimal design solution was proposed.

韩国传统音乐沉浸在丰富的传统文化国乐中，是艺术表现力的迷人体现。本研究采用声学测量、计算机模拟和主观感知调查，对国乐厅进行了综合评估。评估重点关注混响、清晰度、空间印象和偏好，揭示塑造沉浸式国乐体验的秘密。通过复杂的计算机模拟和听觉化，将国乐表演的体验精心呈现在生活中，通过将舞台体积比例从-20%调整到+20%，并修改室内材料，包括墙壁、天花板和侧面，允许在不同的条件下进行探索反射器。尽管国乐厅的混响时间（RT）、早期衰减时间（EDT）和双耳质量指数（BQI）值相对较低，但影响声环境的主导因素是声强（G）的影响。音乐清晰度（C80）值并未显示出与混响时间成反比。此外，韩国传统音乐和西方古典音乐之间的流派差异并没有显着影响听众对混响、清晰度和空间印象的感知和满意度。因此，国乐厅可以遵循与西方交响乐厅相同的声学设计标准，因为这项研究发现人们以同样的方式感知它们。在这项研究中，发现声音强度与感知指标密切相关。通过侧壁和天花板的材料和结构变化，可以增强听众对声学环境的感知和偏好。这些变化改善了低频的增强，同时增强了侧面反射的相对效果。此外，增强材料的反射和空间特性有效地改善了听众的偏好。基于这些发现，提出了最佳设计解决方案。
