DESCRIPTION (provided by applicant): The goal of this research project is to establish the use of temporal resolution data in hearing-aid research for eventual use in hearing-aid fittings. One reason adults with hearing loss exhibit poorer speech recognition than normal hearing adults might be that current amplification may not always provide sufficient access to the temporal cues in speech. Current hearing-aid fitting methods attempt to maximize speech intelligibility, speech audibility, or restore normal loudness but might fall short of those goals. Incorporating measures of temporal resolution could lead to improved speech recognition. To facilitate the use of temporal-resolution data in the fitting of hearing aids, this project will obain measures of temporal resolution under conditions of amplification for the first aim. These data will be compared to measures of temporal resolution obtained for listeners with normal-hearing sensitivity. This methodology will allow us to test the ability of current hearing-aid fitting methds to provide access to temporal cues and to restore normal temporal resolution. The second aim will evaluate the effectiveness of restoring normal temporal resolution to optimize sentence recognition. The objective is to gain insight into what measures of temporal resolution can be used to optimize speech understanding. By knowing this information, hearing-aid fittings could be optimized to provide access to temporal information; possibly leading to improved speech recognition for listeners with hearing loss. PUBLIC HEALTH RELEVANCE: The proposed research is relevant to public health because it address the communication difficulties experienced by individuals with hearing loss. Specifically, the goal of this project is to advance the optimization of hearing aid amplification.

描述（由申请人提供）：该研究项目的目标是在助听器研究中建立时间分辨率数据的使用，以最终用于助听器验配。患有听力损失的成年人比听力正常的成年人表现出较差的语音识别能力的原因之一可能是电流放大可能并不总是能够提供对语音中的时间线索的足够访问。当前的助听器验配方法试图最大化语音清晰度、语音可听度或恢复正常响度，但可能达不到这些目标。 结合时间分辨率的测量可以改善语音识别。为了促进时间分辨率数据在助听器验配中的使用，该项目将在放大条件下获得时间分辨率的测量，以实现第一个目标。这些数据将与为具有正常听力敏感性的听众获得的时间分辨率测量值进行比较。这种方法将使我们能够测试当前助听器验配方法提供访问时间线索并恢复正常时间分辨率的能力。第二个目标将评估恢复正常时间分辨率以优化句子识别的有效性。目的是深入了解哪些时间分辨率测量可用于优化语音理解。通过了解这些信息，可以优化助听器配件以提供对时间信息的访问；可能会改善听力损失听众的语音识别能力。 公共卫生相关性：拟议的研究与公共卫生相关，因为它解决了听力损失者所经历的沟通困难。具体来说，该项目的目标是推进助听器放大的优化。
