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障碍之一，即使在符合OSHA标准的工作场所也是如此。职业性听力损失的预防是国家职业研究议程（NORA）的重中之重。本提案旨在继续进行噪音每日暴露监测（DEMON）研究，该研究是一项独特的干预措施，通过使用一种创新技术（QuietDose）来预防NIHL，该技术可以连续记录听力保护内的噪音暴露水平。在研究的第一阶段，已经招募了干预对象和对照，并定期下载噪音暴露。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（在强制性和自愿使用设置中），更好地了解噪音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），并将听力保护的有效衰减与在单一时间点进行的“拟合测试”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.
