本研究的假设是，听觉训练将允许双峰患者更好地结合助听器(HA)提供的低频声学信息和人工耳蜗(CI)提供的电信息，从而最大化结合声(A)和电(E)刺激(EAS)的好处。在听力训练前后，对7名双峰患者进行了安静或在+5分贝信噪比下多人交谈时的表现进行评估。表演测量包括识别元音和辅音、cnc单词、句子、语音性别和情绪。在A-单独、E-单独和联合EAS条件下评估基线表现，每周一次，持续三周。语音对比训练方案被用来促进语音感知学习。患者在家中训练，每天1小时，每周5天，连续4周，同时打开CI和HA设备。在训练第4周和训练结束后1个月重新测量运动成绩。训练后，在E和EAS条件下，元音、辅音和CnC词的识别都有显著提高。E组的改善幅度与EAS组相当。训练结束一个月后，改善的表现基本保持不变。在本研究中采用的形式的听觉训练可以通过提高E-Alone的表现来改善双峰患者的整体语音理解能力。
The hypothesis of the present study was that auditory training would allow bimodal patients to better combine the low-frequency acoustic information provided by a hearing aid (HA) with the electric information provided by a cochlear implant (CI), thus maximizing the benefit of combining acoustic (A) and electric (E) stimulation (EAS). Performance in quiet or in the presence of a multi-talker babble at + 5 dB SNR was evaluated in seven bimodal patients before and after auditory training. The performance measures comprised identification of vowels and consonants, CNC words, sentences, voice gender, and emotion. Baseline performance was evaluated in the A-alone, E-alone, and combined EAS conditions once per week for three weeks. A phonetic-contrast training protocol was used to facilitate speech perceptual learning. Patients trained at home 1 hour/day, 5 days/week, for 4 weeks with both their CI and HA devices on. Performance was re-measured after the 4th weeks of training and one month after training stopped. After training, there was significant improvement in vowel, consonant, and CNC word identification in the E and EAS conditions. The magnitude of improvement in the E condition was equivalent to that in the EAS condition. The improved performance was largely retained one month after training stopped. Auditory training, in the form administered in this study, can improve bimodal patients’ overall speech understanding by improving E-alone performance.
