A patient who uses the Ineraid cochlear implant, and who has hearing thresholds less than 50 dB HL for frequencies under 500 Hz in his nonimplanted ear, was asked to match the pitch of low-frequency signals presented to his two ears. The patient produced pitch matches, for frequencies of 125, 200, and 300 Hz presented to his most apical electrode, that were slightly higher than the reference frequency. When signals of fixed frequency were presented to electrodes located in successively more basal cochlear locations, pitch increased in an orderly fashion--an average of 57 Hz (range = 31-87 Hz) for each change in electrode location.
一名使用Ineraid人工耳蜗的患者，其未植入耳在500Hz以下频率的听力阈值低于50dB HL，被要求匹配呈现给他双耳的低频信号的音高。对于呈现给他最顶端电极的125Hz、200Hz和300Hz频率，该患者产生的音高匹配略高于参考频率。当固定频率的信号呈现给位于耳蜗中依次更靠近基部位置的电极时，音高以有序方式增加——电极位置每变化一次，平均增加57Hz（范围 = 31 - 87Hz）。
