The Nucleus 22-electrode cochlear implant should be fitted individually for both pitch and loudness. Loudness is related to the charge delivered, and is usually controlled by current amplitude. In special cases the loudness may be influenced by stimulation mode and pulse width. 3 examples demonstrate optimal fitting with low current intensities, using these possibilities. In addition the threshold level and comfortable level date were analysed over a 2-year period. No significant changes were found, indicating that electrical stimulation caused no damage to the remaining auditory nerve fibres.
22电极核型人工耳蜗应针对音高和响度进行个性化调试。响度与传递的电荷有关，通常由电流幅度控制。在特殊情况下，响度可能会受到刺激模式和脉冲宽度的影响。通过3个例子展示了利用这些可能性在低电流强度下的最佳调试。此外，还分析了2年期间的阈值水平和舒适水平数据。未发现显著变化，这表明电刺激未对剩余的听神经纤维造成损伤。
