We review the signal-processing strategies of three of the most common cochlear implants in use today, the single-channel House, the multichannel Nucleus, and the Ineraid devices. The results of 65 postlinguistically-deafened patients tested at The University of Iowa are reviewed. The tests include everyday sound, accent, word and sentence recognition, as well as noise/voice differentiation. For all tests, patients with the Nucleus and Ineraid cochlear implants outperformed those with the House implant. In general, selection criteria should focus on comparing the performance of Patients who have already received an implant. Prelinguistically-deafened adults are typically not good cochlear-impact candidates. Cochlear-implant teams should be aware of the enormous time commitment for testing and rehabilitation of these patients, and be prepared to handle frequent implant breakdowns. Nevertheless, cochlear-implant patients have been helped significantly be these devices.
我们回顾了当今使用的三种最常见的人工耳蜗的信号处理策略，即单通道豪斯人工耳蜗、多通道核人工耳蜗和英纳瑞德装置。回顾了在爱荷华大学对65名语后聋患者进行测试的结果。测试包括日常声音、口音、单词和句子识别，以及噪音/语音辨别。在所有测试中，使用核人工耳蜗和英纳瑞德人工耳蜗的患者表现优于使用豪斯人工耳蜗的患者。一般来说，选择标准应侧重于比较已接受植入的患者的表现。语前聋的成年人通常不是人工耳蜗植入的理想候选人。人工耳蜗植入团队应意识到对这些患者进行测试和康复需要投入大量时间，并准备好处理频繁出现的植入故障。尽管如此，人工耳蜗还是极大地帮助了这些患者。
