摘　　要：声学缩尺模型在声频工程设计中扮演着重要角色,设计者利用缩尺模型,可以准确模拟厅堂内波动声学现象,辅助分析厅堂建筑中的混响时间、声波的吸收与扩散特性、声脉冲响应及声场均匀性分布情况等指标,检测是否会出现音质缺陷,实现厅堂建筑在建成前的可听化,并可利用测试数据对原设计方案进行修正及可行性调整。Acoustic scale model plays an important role in audio engineering design.By using the scale model,designers can accurately simulate the acoustic wave phenomena in the hall,analyze the reverberation time,impulse response,sound absorption characteristics,diffusion characteristics and sound field distribution of hall buildings,detect whether there is a sound quality defect,make hall buildings audible before they are built,and use the test data to modify the original design scheme and adjust the feasibility.
