测试不同声学环境对虚拟音乐舞台感知的影响，验证实验室条件对实验结果可靠性的重要性。
Effect of laboratory conditions on the perception of virtual stages for music
- 对比3种声学环境下的虚拟音乐舞台感知效果
- 吸声良好的听音室与混响室的差异低于可察觉阈值
- 吸声不足的听音室会使虚拟声音被感知为更响亮
本文报告了针对定制听音室中增强声学实验的关键初步发现，解决了确保高敏感度实验设置下感知有效性与实验严谨性的核心挑战。研究评估了三种不同房间声学条件对音乐虚拟舞台感知的影响：消声室、吸声不足的定制听音室，以及具备理想吸声的定制听音室。结果显示，消声室与吸声良好的听音室中，总声与虚拟声之间的差异低于刚可觉察差异（JND），表明虚拟声音未被感知为过响；而吸声不足的听音室中，该差异高于JND，导致虚拟声音被感知为更响。本研究初步验证了评估定制听音室声学条件的方法论可行性。后续工作将包含更全面的结果分析，涵盖不同声源的影响。关键仿真结果的补充音频文件可在https://zenodo.org/records/15579861 获取。
原文摘要 · Abstract (English)
This manuscript presents initial findings critical for supporting augmented acoustics experiments in custom-made hearing booths, addressing a key challenge in ensuring perceptual validity and experimental rigor in these highly sensitive setups. This validation ensures our proposed methodology is sound, guarantees the reliability of future results, and lays the foundational groundwork for subsequent perceptual studies and the development of robust guidelines for laboratory design in virtual acoustics research. A preliminary study on the effect of the acoustical conditions of three different rooms on the perception of virtual stages for music is presented: an anechoic room, a custom-made hearing booth with insufficient sound absorption, and another custom-made hearing booth with achievable sound absorption. The goal of this study is to assess the impact of these different conditions on the perception of virtual stages for music. The results show that the anechoic room and the hearing booth with achievable sound absorption have a difference between the total sound and the virtual sound below the just-noticeable difference, which means that the virtual sound is not perceived louder than it should. In contrast, the hearing booth with insufficient sound absorption has a difference above the just-noticeable difference, which means that the virtual sound is perceived louder than it should. This study provides a preliminary validation of the proposed methodology for assessing the acoustical conditions of custom-made hearing booths in stage acoustics experiments. Future work will include a more comprehensive analysis of the results, including the effect of different sound sources.
