BACKGROUND
Farm operators experience exposure to high noise and high prevalence of noise-induced hearing loss, but use of hearing protection in this worker group is low. The purpose of this study was to test a brief intervention to increase farm operators' use of hearing protection.
METHODS
In this one-group pre- and post-test study, a random sample of 32 members of a farmers' organization was supplied a variety of hearing protectors. Participants received an assortment of hearing protectors by mail with manufacturer's instructions for use.
RESULTS
Mean pre-intervention hearing protector use when in high noise in this group was 23% (SD 29). Of the 32 participants, 27 (84%) were exposed to hazardous noise during the study period. Post-intervention mean use of HPDs was 64%, an increase of 41% (t = 5.26, P < 000).
CONCLUSION
Results of this study suggest that overall, hearing protectors were acceptable to farm operators, and that a brief mailed intervention is feasible.
背景
农场经营者会接触到高强度噪声，并且噪声引起的听力损失的发生率很高，但该作业人群对听力保护用具的使用率很低。本研究的目的是测试一项增加农场经营者使用听力保护用具的简短干预措施。
方法
在这项单组前后测试研究中，农民组织的随机 32 名成员接受了各种听力保护器。参与者通过邮件收到了各种听力保护器，并附有使用说明书。
结果
在该组人群中，当处于高强度噪声环境时，平均干预前的听力保护器使用率为 23%（标准差 29）。在研究期间，32 名参与者中有 27 名（84%）接触到了危险噪声。干预后，HPD 的平均使用率为 64%，增加了 41%（t=5.26，P<0.000）。
结论
本研究结果表明，总的来说，听力保护器受到农场经营者的认可，并且简短的邮寄干预措施是可行的。
