DESCRIPTION (provided by applicant): Three sets of experiments are proposed that address clinically-relevant questions for the management of hearing-impaired persons. The information obtained will assist in deciding which device (hearing aid, traditional cochlear implant, or short-electrode cochlear implant) is most appropriate for a particular patient. The project will also address the question of whether a device is performing adequately in the transmission of speech cues to the patient. Specifically, the project will 1) obtain speech recognition data from normal-hearing listeners using a simulation of the short-electrode cochlear implant to determine which types of hearing loss configurations might be appropriate candidates for this device; 2) to obtain speech recognition in noise data from listeners with cochlear implants and hearing aids to determine the potential advantages or disadvantages of a cochlear implant (both short- and long-electrode) for various degrees of hearing loss; and 3) to use a direct test of the ability to perceive the spectral and temporal cues of speech to predict the abilities of hearing aids and cochlear implants to recognize speech.

描述（由申请人提供）：提出了三组实验，以解决听障患者管理的临床相关问题。所获得的信息将有助于决定哪种设备（助听器，传统人工耳蜗植入或短电极人工耳蜗植入）最适合特定患者。该项目还将解决设备是否在向患者传输语音提示方面表现充分的问题。具体而言，该项目将1）使用短电极人工耳蜗植入物的模拟从正常听力的听众获得语音识别数据，以确定哪些类型的听力损失配置可能是该设备的适当候选者; 2）从具有耳蜗植入物和助听器的收听者获得噪声数据中的语音识别，以确定耳蜗植入物的潜在优点或缺点（短电极和长电极）;以及3）使用感知语音的频谱和时间线索的能力的直接测试来预测助听器和耳蜗植入物识别语音的能力。
