| 摘 要： | 人工耳蜗是一种帮助重度和极重度听力损失者恢复听觉的电子装置。人工耳蜗信号处理策略是人工耳蜗的关键技术之一,决定了人工耳蜗电极输出的信号特征。介绍了电刺激听觉机理,按照时间顺序对主要的人工耳蜗信号处理策略进行介绍,并从听觉感知模型理论的角度对过去40年中在人工耳蜗信号处理策略研究上取得的进展进行深入探讨,最后对未来的人工耳蜗信号处理策略的研究方向提出展望。

| Abstract: | Cochlear implant（CI） is an electronic device that provides partial hearing to severely to profoundly hear-ing-impaired people.The signal processing strategy is one of the key technologies for CI.The strategy determines the characteristic of the output signal from the electrode of the implant.The mechanism of electric hearing is introduced firstly.Then,the research progress of the CI signal processing strategy in the last 4 decades is investigated based on the auditory perception model and presented in chronological order.Finally,the research direction on the strategy is prospected. |
