Research on the communication and academic achievement of children receiving cochlear implants (Cl) shows that these children become functional members of the hearing community alongside other children with less severe hearing loss who wear hearing aids (HAs). The extent to which children with CIs have similar functional capabilities will be addressed in this research program. We will obtain data on non-speech auditory perception, speech perception, music perception, speech, language, reading skills and service provision for a group of 7 and 8 year old children fitted with unilateral, bimodal or bilateral CIs. These data will be compared qualitatively and quantitatively with mild to severe hard of hearing (HH) age mates. This aim will lead to evidence-based clinical guidelines in determining candidacy criteria for cochlear implants or hearing aids. Recently, CIs that preserve residual acoustic hearing (hybrid devices) have been shown to provide hearing benefits to adults with some residual hearing but, these devices have not yet been used with children. In this study, children who are 5 to 15 years of age with moderate to severe hearing loss will receive a hybrid cochlear implant. Speech perception, speech production, language, music perception outcomes will be compared to bimodal and HH children. This aim explores an alternative for children who have some residual hearing, but are not benefitting from conventional hearing aids, to simultaneously take advantage of electric stimulation and their natural acoustic hearing. Aim 3 evaluates the feasibility implanting children with profound deafness with a short electrode in one ear and a standard-length electrode in the other ear. The purpose is an attempt to preserve regions of the cochlear partition future medical interventions in the ear with the short electrode. A within-subject design will evaluate equivalency between the ear with the short electrode array and the ear with the standard-length array on speech perception and electrophysiological measures.

对接受人工耳蜗植入 (Cl) 的儿童的沟通和学业成绩的研究表明，这些儿童与其他佩戴助听器 (HA) 的听力损失较轻的儿童一样，成为听力社区的功能成员。本研究计划将探讨患有 CI 的儿童具有相似功能能力的程度。我们将为一组装有单侧、双峰或双侧 CI 的 7 岁和 8 岁儿童获取有关非言语听觉感知、言语感知、音乐感知、言语、语言、阅读技能和服务提供的数据。这些数据将与轻度至重度听力困难 (HH) 年龄的伴侣进行定性和定量比较。这一目标将产生基于证据的临床指南，以确定人工耳蜗或助听器的候选标准。 最近，保留残余声学听力的 CI（混合设备）已被证明可以为具有一定残余听力的成年人提供听力益处，但这些设备尚未用于儿童。在这项研究中，5 至 15 岁患有中度至重度听力损失的儿童将接受混合人工耳蜗植入。言语感知、言语产生、语言、音乐感知结果将与双峰和 HH 儿童进行比较。这一目标为有一些残余听力但无法从传统助听器中受益的儿童探索一种替代方案，以同时利用电刺激和自然听觉。 目标 3 评估在重度耳聋儿童的一只耳朵中植入短电极并在另一只耳朵中植入标准长度电极的可行性。目的是尝试通过短电极保留耳蜗分区的区域，以便将来对耳朵进行医疗干预。受试者内设计将评估带有短电极阵列的耳朵和带有标准长度阵列的耳朵在言语感知和电生理测量方面的等效性。
