室内音乐现场的声环境分析与改善

Analysis and Improvement of the Acoustic Environment of Live Houses

  • 摘要: 室内音乐现场即“Live House”的声学设计对观演体验有着重要影响,其非传统的观演方式使其在声学设计上不同于传统观演建筑。作者从观众主观调查和演出人士访谈得出长沙、上海、广州多地的场所评价情况,从中选取了两个好评票数最多和两个差评票数最多的场所,对其进行声学测量,通过比较分析其混响时间T30等数据发现该类场所满场与空场两种使用状态下声学指标有显著差异,好评率高的场所在空场时低频T30时值低于中高频T30时值,其满场时各频率T30时值相近且较短。论文通过对不同使用情况、室内装修材料的分析,结合模拟结果,建议室内音乐现场应采用可变吸声的声学设计,并重视吸声材料的低频吸收性能,为该类场所的声学设计与改造提供了参考。

     

    Abstract: The acoustic design of Live Houses has an important impact on audience perception, and its non-traditional performance style makes its acoustic design different from that of traditional performance venues. The author draws from subjective audience surveys and interviews with performers to evaluate venues in Changsha, Shanghai, and Guangzhou. From these venues, two venues with the highest number of favorable votes and two with the highest number of unfavorable votes were selected for acoustic measurements. The authors found significant differences in acoustic metrics between full and empty venues by comparing and analyzing T30 and other data. Venues with high favorable ratings have lower low-frequency T30 than medium- and high-frequency T30 when the venue is empty, and the T30 values at each frequency in a full venue are more similar and shorter. Through the analysis of different use cases and interior materials, combined with simulation results, the article suggests that variable sound absorption design should be adopted for this type of venue, emphasizing the low-frequency absorption performance of sound-absorbing materials. This provides a reference for the acoustic design and reconstruction of such venues.
