Daily Exposure Monitoring Intervention to Prevent Hearing Loss

描述（由申请人提供）：噪声性听力损失（NIHL）仍然是最常见的职业疾病之一，即使在符合OSHA的工作场所也是如此。预防职业性听力损失是国家职业研究议程（诺拉）的首要任务。该提案旨在继续进行每日噪声暴露监测（DEMON）研究，这是一项通过使用创新技术（QuietDose）来预防NIHL的独特干预研究，该技术可连续记录听力保护装置内的噪声暴露水平。在研究的第一阶段，干预对象和控制已被招募和定期下载的噪声暴露正在发生。DEMON研究的第二阶段将继续跟踪这一独特的队列，以确定干预措施的有效性（在强制和自愿使用环境中），更好地了解噪声暴露与听力损失之间的剂量反应关系（包括脉冲噪声的作用），并将听力保护随时间的有效衰减与在单个时间点进行的“适合测试”进行比较。

DESCRIPTION (provided by applicant): Noise-induced hearing loss (NIHL) continues to be one of the most common occupational disorders, even in OSHA compliant workplaces. Prevention of occupational hearing loss is a top priority of the National Occupational Research Agenda (NORA). This proposal is to continue the Daily Exposure Monitoring of Noise (DEMON) Study, a study of a unique intervention to prevent NIHL by use of an innovative technology (QuietDose) that records noise exposure levels inside of hearing protection on a continuous basis. In the first phase of the study, intervention subjects and controls have been recruited and regular downloading of noise exposures is occurring. The second phase of the DEMON study will continue to follow this unique cohort in order to determine the effectiveness of the intervention (in both a mandatory and voluntary use setting), better understand the dose response relationship between noise exposure and hearing loss (including the role of impulsive noise) and also compare the effective attenuation of hearing protection over time with "fit tests" done at a single point in time.
