摘　　要：本文对三维声基于对象音频渲染的响度预估和控制开展研究,将基于对象音频渲染拆解为作为静态对象的声床渲染和单个音频对象动态渲染两个实验,在静态对象渲染实验中以12个测试序列分析了7.1+4H、5.1和2声道配置下相对于5.1+4H的响度变化,在动态对象渲染实验中以四款渲染插件和12个测试序列分析了渲染前后响度的变化。This paper studies the loudness prediction and control of object-based audio rendering in 3D audio.Object-based audio rendering is divided into two experiments:sound bed rendering as a static object and dynamic audio object rendering.In the static object rendering experiment,the loudness under 7.1+4H,5.1 and 2-channel configurations relative to that under 5.1+4H are analyzed with 12 test materials.In the dynamic object rendering experiment,four rendering plug-ins and 12 test materials were used to analyze the change of loudness before and after rendering.
