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）：2000 年美国人口普查中，65 岁以上的美国人有 3500 万，占美国人口的 12.4%。在美国，大约三分之一的 65 岁以上老人（即大约 1200 万美国人）患有严重的听力损失，足以使他们成为助听器候选人。然而，在能够从助听器中受益的人中，只有约 20% 的人真正寻求助听器，而在确实寻求助听器的人中，只有约 40-60% 的人对助听器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问题：他们可以听到语音，但无法理解。当背景中有竞争声音（通常是其他语音）时尤其如此。尽管现代助听器为老年人提供了显着的好处，但为了将辅助言语交流恢复到正常或接近正常的表现水平并优化成功的机会，语音信噪比需要大幅提高。对于许多老年人来说，当代助听器技术无法充分提高语噪比。解决这个问题的另一种方法是训练老年人更好地利用现有语音噪声比中的信息。目前的提案继续我们在这种听觉训练方法方面的工作。具体来说，我们开发了一种创新的词汇驱动的基于单词的听觉训练方案，该方案已被反复证明在受控实验室条件下是有效的。我们的目标是将该协议从有效的实验室系统转变为针对老年人的有效的家庭听觉训练系统。这一转变的第一步是对训练方案的最佳剂量和持续时间进行额外的实验室研究。同时，还将开发家庭系统平台。最后，将使用三分支并行设计对对照组、安慰剂训练组和实验训练组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抱怨是他们可以听到语音，但无法理解，尤其是当背景中有竞争声音时。为了对老年人有效，助听器必须解决这一常见问题并提高言语理解能力。听觉训练是补充助听器带来的好处的一种方法，而家庭听觉训练方法对老年人的有效性是该项目的重点。
