Experiments are proposed that address clinically relevant questions for the management of hearingimpaired patients. The information obtained will assist in deciding which approach for cochlear implantation is most appropriate for a particular patient. Considerable evidence is accumulating that for many patients the preservation of residual acoustic hearing, in addition to the stimulation provided by a cochlear implant, can provide important advantages compared to using only a hearing aid, or only a cochlear implant. One striking advantage is observed for understanding speech in background noise. In addition, this combined acoustic plus electric (A + E) hearing can expand the range of patients that can benefit from electrical stimulation, many of whom were unable to receive adequate benefit from a hearing aid. The proposed studies will continue our ongoing investigation of A + E hearing using the existing Hybrid (short-electrode) device as well as a new generation of longer, less-traumatic electrodes. The advantages and shortcomings of each approach will be measured in terms of preservation of hearing as well as speech understanding in quiet and in noise, for various patients. The goal is to develop eligibility criteria for the different device types, based upon the expected outcomes for various patient characteristics. Additional experiments are described that are designed to discover the mechanisms by which acoustic plus electric stimulation is integrated as an auditory sensation and what factors determine the success of the A + E approach in individual patients.

建议进行实验，以解决与临床相关的听障管理问题。 病人。所获得的信息将有助于决定采用哪种方法植入人工耳蜗。 是最适合特定病人的。越来越多的证据表明，对许多患者来说 除了人工耳蜗提供的刺激外，保留残留的声音听力， 与只使用助听器或只使用人工耳蜗相比，可以提供重要的优势。一 在理解背景噪声中的语音时，观察到显著的优势。此外，这两者结合在一起 声加电(A+E)听力可以扩大患者的范围，可以受益于电 刺激，其中许多人无法从助听器中获得足够的好处。建议数 研究将继续我们正在进行的使用现有混合(短电极)A+E听力的研究 该设备以及新一代更长、创伤更小的电极。优势和劣势 每种方法的听力和语言理解的保存情况将在 安静和嘈杂，适合不同的病人。目标是为不同的设备类型制定资格标准， 基于不同患者特征的预期结果。其他实验包括 描述了旨在发现声加电刺激的机制 整合为一种听觉感觉以及哪些因素决定了A+E方法在 个别病人。
