Abstract
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.
摘要
15名患者一只耳朵植入了人工耳蜗，另一只耳朵佩戴了助听器，他们接受了在电刺激（E）、声刺激（A）以及电声联合刺激（EAS）条件下的言语、旋律识别和语音辨别测试。当把声学信息添加到电刺激信息中时，在安静环境下的单词和句子识别测试以及噪声环境下的句子识别测试中，表现提高了17 - 23个百分点。平均而言，EAS患者在CNC单词测试中比单侧植入人工耳蜗的患者得分更高。虽然最佳的EAS患者表现并未超过最佳的单侧植入人工耳蜗患者，但在言语识别测试中，达到非常高分的EAS患者比例高于单侧植入人工耳蜗的患者。
