DESCRIPTION (provided by applicant): In the 2000 U.S. Census, 35 million Americans over 65 years of age were counted, representing 12.4% of the U.S. population. Approximately one-third of those over age 65 in the U.S., or roughly 12 million Americans, have a significant hearing loss that is sufficient to make them hearing-aid candidates. Yet, only about 20% of those who could benefit from hearing aids actually seek them out and, of those who do seek them out, only about 40-60% are satisfied with them and use their hearing aids regularly. To be successful, hearing aids must address the most common communication complaint of older adults with impaired hearing: they can hear speech, but can't understand it. This is especially true when there are competing sounds, typically other speech, in the background. Although contemporary hearing aids provide significant benefits to older adults, to restore aided speech communication to normal or near-normal performance levels and optimize the chances for success, the speech-to-noise ratio needs to be enhanced considerably. For many older adults, contemporary hearing-aid technologies are unable to enhance the speech-to-noise ratio sufficiently. An alternate approach to this problem is to train the older adult to make better use of the information in the existing speech-to-noise ratio. The present proposal continues our work on such an auditory-training approach. Specifically, we have developed an innovative lexically motivated word-based auditory-training protocol which has been demonstrated repeatedly to be efficacious under controlled laboratory conditions. Our objective is to transition this protocol from an efficacious laboratory system to an effective in-home auditory-training system for older adults. The first step in this transition is an additional laboratory study of the optimal dosing and duration of the training regimen. Concurrently, the platform for the in-home system will be developed. Finally, a clinical trial of the in-home training system will be conducted using a three-branch parallel design with control, placebo-training, and experimental-training groups. PUBLIC HEALTH RELEVANCE: The most common communication complaint of older adults with impaired hearing is that they can hear speech, but can't understand it, especially when there are competing sounds in the background. Hearing aids, to be effective for older adults, must address this common complaint and improve speech understanding. Auditory training represents one approach to supplement the benefits provided by hearing aids and the effectiveness of an in-home auditory-training method in older adults is the focus of this project.

描述（由申请人提供）：在2000年的美国人口普查中，有3500万美国人被计算出65岁以上的美国人，占美国人口的12.4％。在美国65岁以上的人中，约有三分之一（约1200万美国人）的听力损失很大，足以使他们成为助听器候选人。但是，只有大约20％可以从助听器中受益的人实际上会寻找它们，而在那些寻找它们的人中，只有大约40-60％的人对它们感到满意并定期使用助听器。为了取得成功，助听器必须解决听力受损的老年人最常见的沟通抱怨：他们可以听到言语，但听不懂。当背景中有竞争的声音（通常是其他语音）时，尤其如此。尽管当代助听器为老年人带来了重大好处，以恢复与正常或近期表现水平的辅助语音交流并优化成功的机会，但需要大大提高语音与噪声比率。对于许多老年人来说，当代的助听器技术无法充分提高语音与噪声比率。解决此问题的另一种方法是培训老年人，以更好地利用现有的语音与噪声比例中的信息。本提案继续我们在这种听觉训练方法上的工作。具体而言，我们开发了一种创新的词汇动机基于单词的听觉训练协议，该协议已被反复证明是在受控的实验室条件下有效的。我们的目标是将该方案从有效的实验室系统转变为针对老年人有效的家庭听觉训练系统。此过渡的第一步是对训练方案的最佳剂量和持续时间进行的其他实验室研究。同时，将开发家庭系统的平台。最后，将使用带有控制，安慰剂训练和实验训练组的三分支平行设计进行家庭训练系统的临床试验。 公共卫生相关性：听力受损的老年人最常见的沟通投诉是他们可以听到言语，但无法理解，尤其是当背景中有竞争的声音时。助听器对老年人有效，必须解决这一普遍的投诉并提高语音理解。听觉培训是一种补充助听器提供的好处的一种方法，以及在老年人中的家庭听觉训练方法的有效性是该项目的重点。
