The Utah-design multichannel cochlear implant consists of six intracochlear monopolar electrodes, one promontory electrode, and an indifferent electrode. Connection of the intracochlear system to the external sound processor is via a percutaneous pedestal system. Four of the intracochlear electrodes receive simultaneous stimulation. Twenty patients implanted at the University of Utah with more than 1 year of sound processor use were evaluated for the study. All patients wear their sound processors on a daily basis. Seven of the 20 are able to use the telephone without special devices. Nineteen patients were tested with open set CID sentences with an average 42.2% response. A comparison was made between live voice and taped voice open-set spondee word list performance, showing slightly better overall performance with live voice.
犹他设计的多通道人工耳蜗由六个蜗内单极电极、一个岬电极和一个无关电极组成。蜗内系统与外部声音处理器通过经皮基座系统连接。四个蜗内电极同时接受刺激。本研究评估了在犹他大学植入且使用声音处理器超过1年的20名患者。所有患者每天都佩戴声音处理器。20名患者中有7名能够无需特殊设备使用电话。对19名患者进行了开放集CID句子测试，平均反应率为42.2%。对现场语音和录音语音开放集双音节词表表现进行了比较，结果显示现场语音的整体表现略好。
