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.

项目摘要 在有背景噪音的情况下，通过安装人工耳蜗来提高个人的语言理解能力是一项 巨大的挑战虽然可听度有时可能是贝内的限制因素，但更常见的是， 通常导致具有正常听力的个体的声源分离的线索是有限的或不可用的。 该提案将以放大的艾德ILD的形式改变双耳线索，并随着时间的推移将其传递到双侧耳蜗。 植入用户。将检查长时间暴露的影响，包括双耳可塑性的潜力，因为 通过双耳处理的行为和电生理测量的变化来表达。
