This study compares the hearing status and behaviors of Australian farmers from 1994-2001 with those from 2002-2008. Over this period the authors found (1) there was a 12.5% overall improvement in the proportion of farmers with normal hearing in left ears, with the likelihood of a screening participant having normal hearing improving by almost 9% each year; (2) significant improvements in the mean hearing threshold of both ears from 1 to 6 kHz; (3) significantly higher mean hearing thresholds for 35- to 44-year-old farmers exposed to firearms, chainsaws, workshop tools, heavy machinery, and tractors with cabins compared to nonexposed groups; (4) nonuse of hearing protection devices by young farmers (15 to 24 years old), was associated with hearing loss for those using uncabined tractors. Despite a reduction in noise injury, further adoption of noise reduction strategies for specific agricultural work practices is required.
本研究比较了 1994-2001 年和 2002-2008 年澳大利亚农民的听力状况和行为。在此期间，作者发现：（1）左耳听力正常的农民比例总体提高了 12.5%，每年筛查参与者听力正常的可能性提高了近 9%；（2）1-6kHz 双耳平均听力阈值显著改善；（3）与未接触组相比，暴露于枪支、链锯、车间工具、重型机械和带驾驶室的拖拉机的 35-44 岁农民的双耳平均听力阈值显著升高；（4）年轻农民（15 至 24 岁）未使用听力保护装置，与使用无驾驶室拖拉机的农民听力损失有关。尽管噪声损伤有所减少，但仍需要针对特定农业作业实践采用减少噪声的策略。
