厅堂音质辅助设计方法的应用研究

对厅堂音质辅助设计方法的发展历程、研究现状、基础理论和发展趋势进行了概述和讨论,介绍了厅堂的音质要求和设计参量,指出为确保厅堂音质达到设计预定的客观参量,在厅堂声学方案设计完成后,还需采用计算机模拟技术和(或)声学缩尺模型等辅助手段,对声场进行预测,以此为依据对方案不足之处进行修正,并举例说明;同时指出,由于声场复杂性和实验设备及过程的局限性,具体应用时,还需结合理论分析和工程实践进行判断。

Application study of auditorium acoustics assisted design

This paper outlines and discusses the development history, research status, basic theory and development trend of auditorium acoustics assisted design methods, introduces the acoustics requirements and design parameters of the auditorium, and points out what computer simulation technology and (or) acoustic scale model should be adopted to detect sound field characteristics after the acoustics design scheme being completed; then according to the testing results, the scheme would be optimized and modified, moreover some cases are cited as evidences. It also points out that because of the sound field complexity and the limitations of the experimental equipment and processes, the conclusions drawn by acoustics assisted design methods should be further judged by combining with theoretical analysis and engineering practice in the specific applications.
