论文摘要
引入了两个隔离性能指标，区域间隔离（IZI）和程序间隔离（IPI），以评估个人声音区域（PSZ）系统。与常用的声学对比度相比，IZI和IPI概括用于多通道音频，并分别量化声音区域和音频程序的隔离。这两个指标通常不可交流，适用于不同的情况，例如生成黑暗区域（IZI）或最小化And-Audio On-Audio Interference（IPI）。此外，提出了两个带有自由场模拟的示例，并证明了Izi和IPI在评估不同渲染模式和PSZ鲁棒性中评估PSZ性能时的应用。
Two isolation performance metrics, Inter-Zone Isolation (IZI) and Inter-Program Isolation (IPI), are introduced for evaluating Personal Sound Zone (PSZ) systems. Compared to the commonly-used Acoustic Contrast metric, IZI and IPI are generalized for multichannel audio, and quantify the isolation of sound zones and of audio programs, respectively. The two metrics are shown to be generally non-interchangeable and suitable for different scenarios, such as generating dark zones (IZI) or minimizing audio-on-audio interference (IPI). Furthermore, two examples with free-field simulations are presented and demonstrate the applications of IZI and IPI in evaluating PSZ performance in different rendering modes and PSZ robustness.
