The speech perception abilities of deaf children with a single- or multi-channel cochlear implant are compared with those of deaf children who derive substantial benefit from conventional hearing aids. The children with hearing aids have unaided pure-tone thresholds ranging from 90- to 110-dB HL through at least 2000 Hz, and aided thresholds of 30- to 60-dB HL. The group data show that the speech perception scores of the subjects with hearing aids were significantly higher than those of the subjects with implants on a range of speech perception measures. Although a few subjects with implants achieved scores as high as those who used hearing aids, the majority did not. Even though the children with implants receive substantial benefit from their devices, they continue to have limited auditory perception abilities relative to their peers who derive benefit from conventional hearing aids. The data highlight the importance of establishing hearing aid benefit in potential candidates for implant.
将单通道或多通道人工耳蜗植入的聋儿的言语感知能力，与从传统助听器中获得显著助益的聋儿的言语感知能力进行比较。佩戴助听器的儿童，其未佩戴助听器时的纯音听阈在至少2000赫兹范围内为90至110分贝听力级，佩戴助听器后的听阈为30至60分贝听力级。群体数据显示，在一系列言语感知测试中，佩戴助听器的受试者的言语感知分数显著高于植入人工耳蜗的受试者。虽然少数植入人工耳蜗的受试者取得了与使用助听器的受试者一样高的分数，但大多数并非如此。尽管植入人工耳蜗的儿童从其装置中获得了显著助益，但相对于从传统助听器中获益的同龄人，他们的听觉感知能力仍然有限。这些数据凸显了在人工耳蜗植入潜在候选人中确定助听器助益的重要性。
