The benefits of combining a cochlear implant (CI) and a hearing aid (HA) in opposite ears on speech perception were examined in 15 adult unilateral CI recipients who regularly use a contralateral HA. A within-subjects design was carried out to assess speech intelligibility testing, listening effort ratings, and a sound quality questionnaire for the conditions CI alone, CIHA together, and HA alone when applicable. The primary outcome of bimodal benefit, defined as the difference between CIHA and CI, was statistically significant for speech intelligibility in quiet as well as for intelligibility in noise across tested spatial conditions. A reduction in effort on top of intelligibility at the highest tested signal-to-noise ratio was found. Moreover, the bimodal listening situation was rated to sound more voluminous, less tinny, and less unpleasant than CI alone. Listening effort and sound quality emerged as feasible and relevant measures to demonstrate bimodal benefit across a clinically representative range of bimodal users. These extended dimensions of speech perception can shed more light on the array of benefits provided by complementing a CI with a contralateral HA.
将人工耳蜗 (CI) 和助听器 (HA) 结合在对侧耳上对言语感知的益处，在 15 名成年单侧 CI 接受者中进行了检查，这些患者定期使用对侧 HA。采用自身对照设计来评估言语可懂度测试、聆听努力程度评估以及在适用时 CI 单独、CIHA 一起和 HA 单独条件下的声音质量问卷。双模式获益的主要结果定义为 CIHA 和 CI 之间的差异，在安静和噪声条件下的言语可懂度以及在测试的空间条件下的可懂度方面具有统计学意义。在最高测试信噪比下，在可懂度的基础上，努力程度降低。此外，与 CI 单独相比，双模式聆听情况被评定为声音更大、更不刺耳且更不令人不快。聆听努力和声音质量被认为是可行且相关的措施，可以在具有代表性的一系列双模式使用者中展示双模式获益。这些言语感知的扩展维度可以更清楚地说明通过将 CI 与对侧 HA 互补提供的一系列益处。
