由于阵列插入和频率到电极分配的不对称，双侧耳蜗植入用户会经历耳间频率不匹配。为了探索这种不匹配的急性知觉后果，我们测量了9名双侧耳蜗听者在安静时的句子识别，使用实验程序将较差耳朵的频率分配移动±1.5、±3和±4.5毫米。频率分配的变化使双侧句子得分低于单独的较好耳朵，这表明较差的耳朵干扰了较好的耳朵感知。这不是活跃渠道减少的结果；不移频而使电极失活的效果最小。
Bilateral cochlear-implant users experience interaural frequency mismatch because of asymmetries in array insertion and frequency-to-electrode assignment. To explore the acute perceptual consequences of such mismatch, sentence recognition in quiet was measured in nine bilateral cochlear-implant listeners as frequency allocations in the poorer ear were shifted by ±1.5, ±3, and ±4.5 mm using experimental programs. Shifts in frequency allocation >3 mm reduced bilateral sentence scores below those for the better ear alone, suggesting that the poorer ear interfered with better-ear perception. This was not a result of fewer active channels; deactivating electrodes without frequency shifting had minimal effect.
