Residual hearing loss in cochlear implant users is investigated using the mechanical-human-cochlear model. Hearing loss due to stiffening of the round window increases significantly as input frequencies decrease from 3 kHz to 1 kHz but remains constant at lower frequencies, whereas loss due to the presence of an electrode insert becomes significantly higher at lower frequencies ([Formula: see text] kHz). The latter also shifts the characteristic frequency map toward the basal end of the cochlea. In the region away from the end of the electrode insert, cochlear function recovers, but the user still suffers from hearing loss caused by round window stiffening.
使用机械-人-耳蜗模型研究了人工耳蜗使用者的残余听力损失。由于圆窗变硬导致的听力损失随着输入频率从 3 kHz 降低至 1 kHz 而显著增加，但在较低频率时保持不变，而由于电极插入物的存在导致的损失在较低频率时（[Formula: see text] kHz）显著更高。后者还将特征频率图向耳蜗的基底端移动。在远离电极插入物末端的区域，耳蜗功能得到恢复，但患者仍然遭受圆窗变硬引起的听力损失。
