Modifying spatial maps to improve localization

项目摘要 在存在背景噪声的情况下，通过植入人工耳蜗来改善个体fi的语音理解是一种 这是一个巨大的挑战。尽管可听度有时可能是Benefit的限制因素，但更常见的是因为 通常由听力正常的人负责声源分离的线索是有限的或不可用的。 这项提议将改变双耳提示，以Magnified ILDs的形式，并随着时间的推移将它们传递到双边耳蜗 植入用户。将检查长时间暴露的影响，包括双耳可塑性的可能性，如 表现为双耳处理的行为和电生理指标的变化。

PROJECT ABSTRACT Improving speech understanding in the presence of background noise by individuals fitted with cochlear implants is an enormous challenge. Although audibility can sometimes be a limiting factor for benefit, more frequently it is because the cues that are often responsible for sound source segregation by individuals with normal hearing, are limited or unavailable. This proposal will alter binaural cues, in the form of magnified ILDs, and deliver them over time to bilateral cochlear implant users. The effects of prolonged exposure will be examined, including the potential for binaural plasticity, as expressed by changes in behavioral and electrophysiological measures of binaural processing.
