The Burden of occupational hearing loss (HL) is severe, having negative impacts on health care costs and quality of life. There is a strong Need to address barriers to wearing hearing protection devices (HPDs) that can prevent HL. This is especially true in regard to: (1) listening performance decrements that occur while wearing, and (2) the operational environments of first responders whose workplace conditions allow relatively little control over noise. This project will characterize HPD-related performance decrements, their impact on choice to wear HPDs, and how auditory training can be used as a means to alleviate decrements. Our innovative approach will use a paradigm where speech informs subjects to perform specific aspects of a sensorimotor task. This mimics critical communication scenarios in first responders (e.g., a firefighter given speech commands that inform her/his performance on another task). HPD listening will be simulated with a digital filter designed to mimic the attenuation profile of an actual HPD. Electroencephalographic (EEG) data will allow covert examination of neural signatures of ongoing cognitive processes. The approach will allow the characterization of HPD-related performance effects to a level of detail not achieved before, while at the same time maintaining research-to-practice relevance in the mapping of our experimental task to first responder operational situations. AIM 1 will characterize HPD-related decrements in performance. We expect that comparison of HPD and no HPD conditions will reveal the extent to which HPD use impacts multiple dimensions of performance (e.g., speech comprehension, sensorimotor task accuracy, and mental effort). AIM 2 will determine whether or not performance decrements impact choice to wear HPDs. Here, we will allow subjects to voluntarily toggle their simulated HPD on and off, while at the same time manipulating performance incentives to examine how listening difficulty impacts time spent "wearing" hearing protection. AIM 3 will test an auditory training approach to alleviating performance decrements. Here, we will compare effects of auditory training in HPD and no HPD conditions on multiple dimensions of performance. Aim 1 Impact will be in knowledge gains that cannot come from standard survey and focus group methods. The Impact of Aim 2 will be to provide an assessment of how performance decrements impact actual choice to wear. The Impact of Aim 3 will be to provide a means to address performance decrements in HL prevention programs (HLPPs). Relevant NIOSH strategic goals include goals to: "reduce occupational hearing loss", and inform "hearing loss prevention education for employers and workers". NORA sector groups of public safety, construction, and manufacturing have clear relevance. Outputs include publications and conference presentations at interdisciplinary venues that will accelerate research-to-practice directions. Outcomes entail new approaches to addressing HPD use rates, and eventually, reduced occupational HL.

职业性听力损失（HL）的负担是严重的，对医疗保健费用产生负面影响， 生活质量迫切需要解决佩戴听力保护装置（HPD）的障碍， 预防HL。这在以下方面尤其如此：（1）在佩戴时发生的听力性能下降， 以及（2）第一反应者的工作环境，其工作场所条件相对较少 控制噪音。本项目将描述与HPD相关的性能下降，其对选择的影响 佩戴HPD，以及如何使用听觉训练作为缓解衰退的手段。 我们的创新方法将使用一种范式，在这种范式中，语音告知受试者执行特定的 感觉运动任务的各个方面。这模拟了第一响应者中的关键通信场景（例如，一 消防员被给予告知她/他在另一任务上的表现的语音命令）。火奴鲁鲁警局的监听 用设计用于模拟实际HPD衰减曲线的数字滤波器进行模拟。 脑电图（EEG）数据将允许对正在进行的认知活动的神经特征进行隐蔽检查。 流程.该方法将允许对HPD相关性能影响进行详细描述 以前没有实现，同时保持研究与实践的相关性，在我们的地图 第一反应者操作情况的实验任务。 AIM 1将描述HPD相关性能下降的特征。我们希望火奴鲁鲁警局 没有HPD条件将揭示HPD使用对性能多个维度的影响程度 (e.g.,言语理解、感觉运动任务准确性和脑力劳动）。AIM 2将确定是否或 性能下降不会影响佩戴HPD的选择。在这里，我们将允许受试者自愿切换 他们的模拟HPD开和关，同时操纵绩效激励，以研究如何 听力困难会影响“佩戴”听力保护装置的时间。AIM 3将测试听觉训练 缓解性能下降的方法。在这里，我们将比较听力训练在HPD中的效果 并且在性能的多个维度上没有HPD条件。目标1：影响将体现在知识的获得上， 无法通过标准调查和焦点小组方法得出。目标2的影响将是提供一个 评估性能下降如何影响实际的磨损选择。目标3的影响将是 提供一种方法来解决HL预防计划（HLPP）中的性能下降问题。 相关的NIOSH战略目标包括：“减少职业性听力损失”， “雇主和工人预防听力损失教育”。公共安全诺拉部门团体， 建筑业和制造业有着明显的相关性。产出包括出版物和会议 在跨学科场所进行演讲，这将加速研究到实践的方向。结果需要 解决HPD使用率的新方法，并最终减少职业性HL。
