人工混响器为部署在交互式沉浸式系统中的全尺寸室内声学模拟方法提供了一种在计算上可行的替代方法。散射延迟网络(SDN)是一种人工混响器，允许对模拟长方体外壳的几何形状以及模拟声源和麦克风的方向特性进行直接参数控制。本文将SDN混响器的概念扩展到通过光圈耦合的多个腔体。该延伸部允许独立控制耦合外壳的声学特性和连接孔的大小。导出了耦合体积SDN的传递函数。通过绘制的能量衰减曲线与全尺度光线跟踪模型和尺度模型测量结果进行比较，评估了该方法的有效性。
Artificial reverberators provide a computationally viable alternative to full-scale room acoustics simulation methods for deployment in interactive, immersive systems. Scattering delay network (SDN) is an artificial reverberator that allows direct parametric control over the geometry of a simulated cuboid enclosure, as well as the directional characteristics of the simulated sound sources and microphones. This paper extends the concept of SDN reverberators to multiple enclosures coupled via an aperture. The extension allows independent control of the acoustical properties of the coupled enclosures and the size of the connecting aperture. Transfer functions of the coupled-volume SDN are derived. The effectiveness of the proposed method is evaluated in terms of rendered energy decay curves in comparison to full-scale ray-tracing models and scale model measurements.
