This study examined 1984 monitoring audiometric data from U.S. Navy (military and civilian) employees whose workplace required a mandatory hearing conservation program. Median hearing thresholds were compared in U.S. Navy employees, U.S. Army employees also monitored by a hearing conservation program, and a standard population from the First National Health and Nutrition Survey. Age group and frequency-specific comparisons were included. Results at 4 kHz and 6 kHz demonstrated higher median thresholds in the Navy populations that were significantly higher by clinical and statistical criteria. Possible reasons for the differences are given.
本研究对1984名美国海军（军事人员和平民）雇员的听力监测数据进行了检查，这些雇员的工作场所要求实施强制性听力保护计划。将美国海军雇员、同样接受听力保护计划监测的美国陆军雇员以及第一次全国健康和营养调查中的标准人群的听力阈值中位数进行了比较。纳入了年龄组和特定频率的比较。4千赫和6千赫的结果显示，海军人群的听力阈值中位数较高，根据临床和统计标准，显著更高。文中给出了差异的可能原因。
