简单的听觉混合物的感知是随着时间的推移而演变的。例如，一个常见的例子是流分离的“积累”，这是针对音调交替的音调序列观察到的。然而，人们对更复杂的听觉场景（如多人混合声）的感知如何随时间变化知之甚少。以前的数据是一致的想法，分离的能力，从竞争的声音目标说话者迅速提高稳定的线索时，这导致语音清晰度的改善。这项研究检查了听力正常和听力受损的听众这种积累的时间过程。从水平面上的五个位置同时呈现五个数字序列，长度从三到六位不等。在一个位置的同步视觉提示表明哪个序列是每次试验的目标。我们观察到数字识别性能的增强，主要是由目标和掩蔽物之间的混淆减少驱动的，这发生在三到四个数字的过程中。听力损失的听众的表现往往较差;然而，只有微弱的证据表明，这一组的积累减少或减缓。
The perception of simple auditory mixtures is known to evolve over time. For instance, a common example of this is the “buildup” of stream segregation that is observed for sequences of tones alternating in pitch. Yet very little is known about how the perception of more complicated auditory scenes, such as multitalker mixtures, changes over time. Previous data are consistent with the idea that the ability to segregate a target talker from competing sounds improves rapidly when stable cues are available, which leads to improvements in speech intelligibility. This study examined the time course of this buildup in listeners with normal and impaired hearing. Five simultaneous sequences of digits, varying in length from three to six digits, were presented from five locations in the horizontal plane. A synchronized visual cue at one location indicated which sequence was the target on each trial. We observed a buildup in digit identification performance, driven primarily by reductions in confusions between the target and the maskers, that occurred over the course of three to four digits. Performance tended to be poorer in listeners with hearing loss; however, there was only weak evidence that the buildup was diminished or slowed in this group.
