Psychophysical data such as threshold and comfort levels indicate an extensive preservation of auditory nerve fibers. Changes of these data can point to increasing damage of nerve fibres due to long-term electrical stimulation or to obliteration of the cochlea when an intracochlear system is used. Unfavourable levels indicate negative influence on speech comprehension. The psychophysical data and the speech comprehension of 10 patients fitted with a Clark/NUCLEUS cochlear implant in the last 2 years have been analysed. During this period of time the threshold and comfort levels remained almost stable, whereas speech comprehension is still increasing, though to a lesser extent, after 2 years with the implant. These results indicate that the patients suffer neither an increasing destruction of auditory nerve fibres nor severe intracochlear changes.
诸如阈值和舒适度水平等心理物理学数据表明听神经纤维得到了广泛的保留。这些数据的变化可能表明由于长期电刺激导致神经纤维损伤增加，或者在使用耳蜗内系统时耳蜗闭塞。不利水平表明对言语理解有负面影响。对过去两年中接受克拉克/核子耳蜗植入的10名患者的心理物理学数据和言语理解进行了分析。在此期间，阈值和舒适度水平几乎保持稳定，而植入两年后言语理解仍在增加，尽管增幅较小。这些结果表明，患者既没有遭受听神经纤维的持续破坏，也没有发生严重的耳蜗内变化。
