A new 8-electrode prosthesis has been developed for individuals deafened by bilateral auditory nerve tumors (neurofibromatosis-2). Twelve patients have received the multichannel auditory brain stem implant at House Ear Institute since 1992, 11 of whom receive useful auditory sensations. Processor fitting includes scaling and ranking of electrode-specific pitch sensations, and determination of any nonauditory sensations. Two representative patients differing in experience and number of usable electrodes are compared in terms of range of auditory sensations and speech perception performance. An inexperienced patient with two electrodes using a new speech-processing strategy (Speak) performed comparably to an experienced patient with six electrodes using an earlier feature-extraction processor.
一种新型的8电极假体已被开发出来，用于因双侧听神经瘤（神经纤维瘤病2型）而致聋的患者。自1992年以来，12名患者在豪斯耳科研究所接受了多通道听觉脑干植入，其中11人获得了有用的听觉感受。处理器适配包括对电极特异性音调感受进行缩放和排序，以及确定任何非听觉感受。比较了两名在经验和可用电极数量上存在差异的代表性患者的听觉感受范围和言语感知表现。一名使用新言语处理策略（Speak）的仅有两个电极的经验不足患者，其表现与一名使用早期特征提取处理器的有六个电极的经验丰富患者相当。
