许多声源以可预测的方式发出信号。可预测性可以被利用来支持一个源的信号发射与其他源的重叠信号的分离的想法已经表达了很长一段时间。然而，听觉场景分析（阿萨）中的可预测性的强有力的作用的实验证据是稀缺的。最近，由于我们对大脑如何从一系列感觉事件中提取可预测性的看法发生了根本性的变化，关于这一主题的实验和理论工作出现了高潮。基于听觉系统中毫不费力的预测处理，可预测性可用作声源分解的线索变得更加合理。在目前的贡献，经验证据的可预测性在阿萨的作用将进行审查。它将被证明，可预测性影响阿萨时，它是存在于感兴趣的声源（感知前景），当它是存在于其他声源，听众希望忽略（感知背景）。第一个证据指向与年龄有关的障碍，后者的能力将得到解决。此外，它将说明如何影响的可预测性，可以通过客观的听力测试以及主观报告程序，后者的方法通常利用多稳定的性质的听觉感知。将描述研究设计的关键方面，以确保可以明确解释可预测性效应。阿萨内的可预测性的功能作用的可能机制进行了讨论，并将建议与旧加新的启发式分组同时声学信号的类比。
Many sound sources emit signals in a predictable manner. The idea that predictability can be exploited to support the segregation of one source's signal emissions from the overlapping signals of other sources has been expressed for a long time. Yet experimental evidence for a strong role of predictability within auditory scene analysis (ASA) has been scarce. Recently, there has been an upsurge in experimental and theoretical work on this topic resulting from fundamental changes in our perspective on how the brain extracts predictability from series of sensory events. Based on effortless predictive processing in the auditory system, it becomes more plausible that predictability would be available as a cue for sound source decomposition. In the present contribution, empirical evidence for such a role of predictability in ASA will be reviewed. It will be shown that predictability affects ASA both when it is present in the sound source of interest (perceptual foreground) and when it is present in other sound sources that the listener wishes to ignore (perceptual background). First evidence pointing toward age-related impairments in the latter capacity will be addressed. Moreover, it will be illustrated how effects of predictability can be shown by means of objective listening tests as well as by subjective report procedures, with the latter approach typically exploiting the multi-stable nature of auditory perception. Critical aspects of study design will be delineated to ensure that predictability effects can be unambiguously interpreted. Possible mechanisms for a functional role of predictability within ASA will be discussed, and an analogy with the old-plus-new heuristic for grouping simultaneous acoustic signals will be suggested.
