项目摘要

DESCRIPTION (provided by applicant): The long-term goals of the present proposal are to develop individualized, efficient and effective training protocols and materials to maximize cochlear implant patient performance in real-world listening conditions. We hypothesize that targeted contrast training can greatly improve cochlear implant patients' performance for a variety of simulated real-world listening conditions, and that individualized training protocols and materials may be necessary to maximize training outcomes. We further hypothesize that passive learning may not allow cochlear implant patients to receive the full benefit of advanced coding strategies, and that targeted auditory training may help patients access the additional cues provided by novel processing schemes. There are three specific aims in the proposed research. First, we propose to measure the benefits of auditory training in simulated real-world listening conditions, including speech perception in noise, speech perception via telephone, and music perception. Second, we propose to develop individualized, efficient and effective training protocols and materials to maximize training outcomes. Third, we propose to quantify interactions between auditory training and changes to speech processor parameters. While the proposed experiments will evaluate different aspects of auditory training somewhat independently, there are areas of overlapping consideration that may be combined to advance auditory rehabilitation techniques for cochlear implant patients. These proposed experiments have great theoretical significance, as the results will shed light on auditory plasticity in electric hearing and the importance of training when evaluating experimental speech processor parameters. The experiments have even greater clinical significance, as the results will provide strong evidence of the benefits of auditory training, hopefully leading to affordable, efficient and effective rehabilitation that cochlear implant patients can perform at home, using personal computers. We expect that these training approaches, if successful in real-world simulations, will generalize to improved performance outside the lab. As recent advances in implant technology seem to be reaching the point of diminishing returns, auditory training may provide the most cost-effective approach for cochlear implant patients to maximize the benefit of the implant device.

描述（由申请人提供）：本提案的长期目标是开发个性化、高效且有效的培训方案和材料，以最大限度地提高人工耳蜗患者在现实听力条件下的表现。我们假设有针对性的对比训练可以极大地提高人工耳蜗患者在各种模拟现实世界听力条件下的表现，并且可能需要个性化的训练方案和材料来最大限度地提高训练效果。我们进一步假设被动学习可能无法让人工耳蜗患者充分受益于先进的编码策略，而有针对性的听觉训练可能有助于患者获得新颖的处理方案提供的额外线索。拟议的研究有三个具体目标。首先，我们建议衡量在模拟现实世界听力条件下进行听觉训练的好处，包括噪声中的语音感知、电话语音感知和音乐感知。其次，我们建议制定个性化、高效且有效的培训方案和材料，以最大限度地提高培训成果。第三，我们建议量化听觉训练和语音处理器参数变化之间的相互作用。虽然所提出的实验将在一定程度上独立地评估听觉训练的不同方面，但存在一些重叠考虑的领域，可以将它们结合起来以推进人工耳蜗植入患者的听觉康复技术。这些提出的实验具有重大的理论意义，因为结果将揭示电听力中的听觉可塑性以及评估实验语音处理器参数时训练的重要性。这些实验具有更大的临床意义，因为结果将提供听觉训练益处的有力证据，有望使人工耳蜗患者可以在家中使用个人电脑进行经济实惠、高效且有效的康复治疗。我们预计这些训练方法如果在现实世界的模拟中取得成功，将能够推广到实验室外提高性能。由于植入技术的最新进展似乎已达到收益递减的地步，听觉训练可能为人工耳蜗植入患者提供最具成本效益的方法，以最大限度地发挥植入装置的益处。
