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.
