目的：本文比较了语言的发展和言语知觉的儿童与双峰拟合（一只耳朵的人工耳蜗植入和助听器在对侧耳朵）或双边cochlearimplantation.METHODS：参与者是儿童参加了纵向结果的儿童听力障碍研究。在3岁时使用标准化测试评估语言发育。在5岁时评估言语感知。语音是从正面扬声器，和牙牙学语噪声是从前面或从both sides.RESULTS：平均而言，有44个孩子与双峰拟合和49个孩子与双侧人工耳蜗植入体之间的语言结果没有显着差异;控制一系列的人口统计学变量后。人工耳蜗植入激活年龄越早，结果越好。在噪声中，双峰拟合和双侧人工耳蜗植入的儿童之间的言语感知没有显着差异。与听力正常的儿童相比，儿童与人工耳蜗植入体需要一个更好的信噪比，以执行在同一水平，但表现出空间释放掩蔽的相似magnesium.CONCLUSIONS：这项以人口为基础的研究发现，语言分数为儿童与双边植入体高于双峰拟合或那些与单边植入体，但都没有达到显着水平。
OBJECTIVES: This paper compares language development and speech perception of children with bimodal fitting (a cochlear implant in one ear and a hearing aid in the opposite ear) or bilateral cochlear implantation.METHODS: Participants were children enrolled in the Longitudinal Outcomes of Children with Hearing Impairment study. Language development was assessed at 3 years of age using standardized tests. Speech perception was evaluated at 5 years of age. Speech was presented from a frontal loudspeaker, and babble noise was presented either from the front or from both sides.RESULTS: On average, there was no significant difference in language outcomes between 44 children with bimodal fitting and 49 children with bilateral cochlear implants; after controlling for a range of demographic variables. Earlier age at cochlear implant activation was associated with better outcomes. Speech perception in noise was not significantly different between children with bimodal fitting and those with bilateral cochlear implants. Compared to normal-hearing children, children with cochlear implants required a better signal-to-noise ratio to perform at the same level, but demonstrated spatial release from masking of a similar magnitude.CONCLUSIONS: This population-based study found that language scores for children with bilateral implants were higher than those with bimodal fitting or those with unilateral implants, but neither reached significance level.
