项目摘要

Summary Middle-aged adults often report problems understanding speech in adverse listening conditions, even though they typically demonstrate essentially normal results on routine audiological tests. The extent of these self- reported problems can be as great or greater than problems expressed by older adults with considerably more hearing loss. The disconnect between measured and self-perceived hearing problems in middle-aged adults could be due, at least in part, to listening being more effortful for them. Since their problems are not apparent using currently-available assessment measures, clinical audiology has little to offer these individuals in terms of identifying or addressing their hearing problems. The long-term goal of this research is to develop evaluation and treatment methods that focus on functional hearing early in the aging process. Treating hearing problems in midlife could help to reduce the negative outcomes associated with age-related hearing loss (such as cognitive decline and risk of incident dementia). The focus of the project described in this application is on quantifying cognitive load (i.e., effort) required for middle-aged adults to understand speech in the presence of different types of masking sounds. Cognitive load will be quantified using ecologically-valid measures: dual- task costs associated with listening-while-walking; memory for previously heard speech; and subjective ratings of listening effort. This project also will identify the impact of Personal Sound Amplifier (PSAPs) on functional hearing in middle-aged adults with mild hearing loss. These devices, which are sold over-the-counter, are more affordable than traditional hearing aids and so might be more acceptable to these individuals than are conventional hearing instruments. Experiments in the proposed project will determine the effectiveness of selected higher-end PSAPs (when used both binaurally and monaurally) for decreasing listening effort, and for improving speech understanding and spatial hearing ability, in middle-aged adults with mild hearing loss. Testing will be conducted before and after controlled field trials of monaural and binaural PSAP use in order to identify acclimatization effects. Outcomes of this project have the potential to alter when and how we evaluate and treat age-related hearing loss.

概括中年成年人经常报告有问题理解不利的听力条件下的语音，即使他们通常在常规听力学测试中表现出正常的结果。这些自我的程度报告的问题可能比老年人表达的问题大得多或更大听力损失。中年成年人的测量与自我感知的听力问题之间的断开连接至少部分是由于倾听对他们更加努力的原因。由于他们的问题并不明显使用当前可用的评估措施，临床听力学几乎没有提供这些人确定或解决他们的听力问题。这项研究的长期目标是制定评估以及重点是在衰老过程早期功能听力的治疗方法。治疗听力问题在中年，可以帮助减少与年龄相关的听力损失相关的负面结果（例如认知能力下降和出现痴呆症的风险）。本应用程序中描述的项目的重点是量化中年成年人需要在存在的情况下了解语音所需的认知负荷（即努力）不同类型的掩盖声音。认知载荷将使用生态播种的措施进行量化：双重与聆听时相关的任务成本；以前听过的演讲的记忆；和主观评分听力努力。该项目还将确定个人声音放大器（PSAP）对功能的影响中年成年人的听力轻度听力损失。这些设备在非处方出售，更多比传统的助听器负担得起，因此这些人可能比常规的听力工具。拟议项目中的实验将确定选定的高端PSAP（同时使用双耳和单毛）来减少听力工作，并且在轻度听力损失的中年成年人中，提高语音理解和空间听力能力。在对照和双耳PSAP使用的受控现场试验之前和之后，将进行测试确定适应效应。该项目的结果有可能改变何时以及如何评估并治疗与年龄有关的听力损失。
