Acoustic Plus Electric Hearing

项目1：声学加电听 人工耳蜗术中保留残余听力已成为一项重要的研究 人工耳蜗术中性能的改进。它不仅提高了植入物的性能 (特别是对于嘈杂的、真实世界的听力条件)，但也允许治疗重症患者 高频听力损失，他们有实质性的低频听力。该项目计划继续进行 这项工作是关于声电(A，E)相结合的听证。除了改善的总体目标之外 对于听力损失的患者护理，这项工作带来了几个独特的研究机会。第一个机会 这是因为将植入这些A-E装置的新患者群体的缘故。绝不可能 以前有过如此高水平的术前残余听力的患者被植入如此大的- 规模项目。同时，我们也看到了语音传输的性能水平 根据以前的文献，短电极令人惊讶。这将使我们能够重新检查一些 关于电刺激由于经络相互作用的局限性的普遍看法。这个 第二个机会出现了，因为短电极混合型种植体分配了低频和中频 语带延伸至耳蜗底的极端位置。因此，我们有一个独特的机会来研究 重映射、神经可塑性和对高度扭曲的位置-频率映射的适应在 耳蜗骨。

Project 1: Acoustic Plus Electric Hearing Preservation of residual acoustic hearing during cochlear implantation has become an important improvement in the performance of cochlear implants. Not only does it improve the performance of implants (particularly for noisy, real-world listening conditions) but also allows the treatment of patients with severe high-frequency hearing loss, who have substantial low-frequency hearing. This project proposes to continue this work on combining acoustic plus electric (A+E) hearing. In addition to the overall goal of improving patient care for hearing loss, several unique research opportunities arise from this work. The first opportunity arises because of the new population of patients that will be implanted with these A+E devices. Never before have patients with such high levels of pre-operative residual hearing been implanted in such a large- scale project. We are at the same time seeing levels of performance for the transmission of speech through the short electrode that are surprising in light of the previous literature. This will allow us to re-examine some of the commonly held beliefs about the limitations of electric stimulation due to channel interaction. The second opportunity arises because the short-electrode Hybrid implant assigns low- and mid-frequency speech bands to extreme basal locations in the cochlea. Thus we have a unique opportunity to study the effects of remapping, neural plasticity, and adaptation to highly-distorted place-frequency maps in the cochlea.
