DESCRIPTION (provided by applicant): Despite the advantages of listening with two ears, localization and spatial segregation of speech and noise remain difficult for patients who use two cochlear implants (CIs) or a CI in combination with a hearing aid. These difficulties may be due to: 1) poor spectral and/or temporal processing, 2) distorted peripheral patterns, and/or 3) poor binaural integration of peripheral patterns. Auditory training may mitigate these deficits. Our long-term goal is to develop training methods that improve CI patients' binaural perception. It is as yet unclear whether training should target unilateral peripheral processing or bilateral integration of peripheral signals or both. We hypothesize that the difference in unilateral performance across ears ("asymmetry") must be reduced to maximize the binaural benefit. Unilateral training with the poorer ear alone, followed by bilateral training will provide the best training outcome. For spatial binaural perception (localization and squelch), we further hypothesize that localization requires greater spatial precision than segregation of speech and noise; improving localization will improve spatial segregation. Localization training, followed by spatial segregation training will provide the best outcomes for spatial hearing. In all three Aims, we will use a crossover experimental design to see whether the training sequence affects outcomes. Auditory training has not been extensively studied in bilateral CI or bimodal listeners, and there are few (if any) targeted rehabilitation programs for these patient groups. By addressing these deficits in research and rehabilitation, the proposed research offer novel approaches to increasingly commonplace difficulties for CI patients. The research seeks to identify the best training approach for bilateral CI and bimodal patients, as well as understand how differences in the peripheral input may influence binaural perception as well as the training outcomes. The conceptual framework addresses different factors that may limit performance: auditory resolution, peripheral representation and/or integration of peripheral inputs. Experiments 1 and 2 address whether unilateral psychophysical or speech training is more effective. Experiments 3 and 4 address a fundamental question facing all bilateral CI and bimodal patients: Is it better to train with one ear or two? Experiments 5 and 6 addresses whether spatial training is task-specific (localization vs. spatial segregation). The proposal is o great clinical significance, as the research will guide efficient training methods to maximize CI users' binaural perception. The research is also of great theoretical significance, as it seeks to better understand connections between psychophysical and speech measures, binaural benefits and unilateral performance, as well as localization and spatial segregation in electric hearing. As advances in CI technology seem to be reaching a point of diminishing returns, auditory training may provide the most cost-effective approach to maximize the benefit of cochlear implantation.

描述（由申请人提供）：尽管有两只耳朵聆听的优点，但对于使用两种耳蜗植入物（CI）或CI与助听器结合使用的患者，语音和噪音的定位和空间隔离仍然很难。这些困难可能是由于：1）光谱和/或时间处理较差，2）外周图模式变形；和/或3）外周图模式的双耳整合不良。听觉训练可能会减轻这些缺陷。我们的长期目标是开发改善CI患者双耳感知的训练方法。目前尚不清楚训练应靶向单方面的外围处理或外围信号的双侧整合还是两者兼而有之。我们假设必须降低耳朵的单侧性能的差异（“不对称”）以最大化双耳益处。单独的耳朵单方面训练，然后进行双边训练，将提供最好的 训练结果。对于空间双耳感知（定位和静止），我们进一步假设定位比语音和噪声的隔离需要更高的空间精度。改善本地化将改善空间分离。随后进行空间隔离训练的本地化培训将为空间听力提供最佳结果。在这三个目标中， 我们将使用跨界实验设计来查看训练序列是否影响结果。在双边CI或双峰听众中，尚未对听觉训练进行广泛的研究，并且这些患者群体几乎没有（如果有）有针对性的康复计划。通过解决研究和康复中的这些缺陷，拟议的研究为CI患者越来越普遍的困难提供了新的方法。该研究旨在确定双侧CI和双峰患者的最佳训练方法，并了解周围输入的差异如何影响双耳的感知以及培训结果。概念框架解决了可能限制性能的不同因素：听觉分辨率，外围表示和/或外围输入的集成。实验1和2解决单方面心理物理或言语训练是否更有效。实验3和4解决了所有双边CI和双峰患者面临的基本问题：用一两只耳朵训练更好吗？实验5和6解决了空间训练是否特定于任务（本地化与空间隔离）。该提议具有很大的临床意义，因为该研究将指导有效的培训方法，以最大程度地提高CI使用者的双耳感知。这项研究也具有重要的理论意义，因为它试图更好地了解心理物理和言语措施，双耳益处和单方面表现以及电气听力中的本地化和空间隔离之间的联系。随着CI技术的进步似乎达到了回报的降低，听觉培训可能会提供最具成本效益的方法，以最大程度地提高人工耳蜗的好处。
