中文摘要:
      声学参量在声场中的分布情况,影响厅堂的音质效果。以一个中型会议室为例,采用Odeon软件,模拟分析了两种声源情况下,材料的布置与形状对中、小型厅堂声场均匀度的影响。结果表明中、小型厅堂后墙吸声材料的布置对均匀度的影响较小;材料的布置与形状对早期衰减时间(Early Decay Time,EDT)与混响时间T30均匀度的影响较大,而对声压级(Sound Pressure Level,SPL)、明晰度C80、清晰度D50与语言传输指数(Speech Transmission Index,STI)均匀度的影响较小;声源对EDT、SPL、D50与STI均匀度的影响较大,而对T30C80均匀度的影响较小。研究结果可为中小型厅堂的音质设计和研究提供参考。
英文摘要:
      The distribution of acoustic parameters in sound field affects the sound quality of the hall. By taking a medium sized meeting room as an example and using Odeon software, the effects of material layout and modeling on the sound field uniformity in small and medium-sized halls are simulated and analyzed under two sound sources. The results show that the arrangement of sound-absorbing materials on the back wall of small and medium-sized halls has little effect on the uniformity; the arrangement and shape of materials have a greater effect on the uniformities of early decay time (EDT) and reverberation time (T30), while have little effect on the uniformities of sound pressure level (SPL), clarity (C80), definition (D50) and speech transmission index (STI); the sound source situation has a greater impact on the uniformities of EDT, SPL, D50 and STI, but has a small impact on the uniformities of T30 and C80. The research results can provide references for the sound quality design and research of small and medium-sized halls.
