中文摘要	本文介绍了电子耳蜗的虚拟通道技术,采用同步或序列方式刺激两个相邻电极对,可产生一个或多个独立、可辨的中间音高,即虚拟通道。该技术利用有限数量的固定电极最大化地产生、传递更丰富的频域音高信息,有效利用了电极间的相互作用,同时也提高电子耳蜗植入者听觉系统的频域分辨率。应用该技术将可能使植入者在音乐欣赏、汉语识别、噪声环境下语音识别等方面有更理想的听力恢复效果,有助于提高电子耳蜗的语音识别效果,使更多电子耳蜗植入者更好地恢复听觉。; This paper discusses virtual channels of cochlear implant, which is produced by simultaneous or sequential activation of adjacent cochlear implant electrodes. Virtual channels create and transfer more available spectral pitch information with the limited number of fixed electrodes, which can be recognized as pitch percepts intermediate to those produced by each electrode separately. This technique not only utilizes the interaction of electrodes but also increases the number of place-pitch steps available to cochlear implant listeners. Virtual channels could be used to realize speech recognition in noisy environment, in enjoying music, and in understanding Chinese language. The study of virtual channels would significantly enhance the traditional cochlear implant therapy and benefit people suffering severe to profound hearing loss.; 中国博士后科学基金资助(20070420377)
