对15例单耳植入人工耳蜗、单耳佩戴助听器的患者进行了电刺激(E)、声刺激(a)和电声联合刺激（EAS）条件下的语音、旋律识别和声音辨别测试。在安静环境下的单词和句子识别测试以及在噪音环境下的句子识别测试中，将声学信息加入到电刺激信息中，成绩提高了17-23个百分点。平均而言，EAS患者在CNC单词上的得分高于单侧人工耳蜗患者。虽然最优秀的EAS患者并没有超过最适合单侧人工耳蜗的患者，但在语音识别测试中获得高分的EAS患者比例高于单侧人工耳蜗患者。版权所有(c) 2007 S. Karger AG，巴塞尔。
Fifteen patients fit with a cochlear implant in one ear and a hearing aid in the other ear were presented with tests of speech and melody recognition and voice discrimination under conditions of electric (E) stimulation, acoustic (A) stimulation and combined electric and acoustic stimulation (EAS). When acoustic information was added to electrically stimulated information performance increased by 17-23 percentage points on tests of word and sentence recognition in quiet and sentence recognition in noise. On average, the EAS patients achieved higher scores on CNC words than patients fit with a unilateral cochlear implant. While the best EAS patients did not outperform the best patients fit with a unilateral cochlear implant, proportionally more EAS patients achieved very high scores on tests of speech recognition than unilateral cochlear implant patients.
