目的：海軍中許多武器噪音暴露的人員，其實也都與國內勞工一樣面臨著高噪音工作環境的暴露，因此本研究的目的，在分析海軍人員聽力損失情形。方法：本研究採前瞻性研究設計，研究對象為北部某一地區之海軍人員，研究期間為2011年1月1日至2011年12月31日，針對同意之受試者進行聽道理學檢查及純音聽力測驗。結果：研究期間總計339位完成收案。研究對象平均年齡為36.28±12.22歲，性別方面以
男性佔居多(85.9%)。BMI<24佔43.0%、BMI為24≦27佔34.6%、BMI≧27佔22.4%；服役年資平均為11.27±9.07年，目前使用噪音防護用具類別中，耳塞佔52.5%，耳罩佔43.85%；工作全程使用防護用具佔20.2%，工作間斷使用防護用具佔79.8%。有吸菸習慣佔29.2%，有嚼檳榔習慣佔3.6%，有固定喝酒習慣佔10.8%。針對左右耳聽力部分，左耳低頻平均聽力值為27.31±12.61分貝，≦25分貝佔57.4%，>25分貝佔42.6%；高頻平均優耳值為32.20±19.07分貝，≦25分貝佔44.3%，>25分貝佔55.7%。右耳低頻平均聽力值為25.67±10.88分貝，≦25分貝佔58.5%，>25分貝佔41.6 %；高頻平均聽力值為31.62±18.89分貝，將其值進行截切點分組，≦25分貝佔48.2%，>25分貝佔51.8%。低頻優耳受損分組 (≦24&≧25)之多元逐步迴歸分析中，相較低頻優耳受損分組≦24者，目前單位年資每增加一年，其低頻優耳受損分組>25之風險為1.055(p<0.001)； BMI≧27相較於BMI<24者，其低頻優耳受損分損>25的風險為2.570(p=0.010)。高頻優耳受損分組 (≦24&≧25)之多元逐步迴歸分析中， BMI≧27相較於BMI<24者，其高頻優耳受損分損>25的風險為6.315(p=0.003)；相較高頻優耳受損分組≦24者，目前單位年資每增加一年，其高頻優耳受損分組>25之風險為1.118(p<0.001)。
結論：本次結果發現在海軍工作人員，不論高低頻聽力，均有相當比例的人員有聽力損失，因此仍需要強化聽力防護工具、環境噪音評估、定期聽力檢查、及聽力衛生教育。

Purpose: The hearing impairment is an important issue in the navy. Our purpose is to explore the prevalence of hearing impairment in naval officers and soldiers in the different environment. Method: The survey adopts prospective study design. The study is conducted in the navy in the northern city in Taiwan from January 1, 2011 to December 31, 2011. The definition of hearing impairment is made as the pure-tone average 25-dB hearing level of pure-tone thresholds at low/midfrequencies (500; 1,000; and 2,000 Hz) and high frequencies (3,000; 4,000; 6,000; and 8,000 Hz). The independent risk factors are investigated using logistic regression.
Results: The 339 participants completed the completed the audiometric examination and structured self-administered questionnaires. The eligible subjects had a mean age of 36.28 ± 12.22 years. The partcipants with low/mid-frequency hearing impairment have more hearing loss in the less than a high school education, whereas no significant differences in other varibles. In the low/mid-frequency, the mean pure tone average of left ear is 27.31 ± 12.61 dB, and the mean pure tone average of right ear is 25.67 ± 10.88 dB. In the high frequency, the mean pure tone average of left ear is 32.20 ± 19.07 dB, and the mean pure tone average of right ear is 31.62 ± 18.89 dB. Controlling for other variables, odds ratios for associations with low/mid-frequency hearing impairment are 1.373 for BMI 24-27 and 25.70 for BMI≧27. Controlling for other variables, odds ratios for associations with high-frequency hearing impairment were 1.003 for BMI 24-27 and 6.315 for BMI≧27. Conclusion: In our study, it is important to strengthen hearing protection, environmental noise monitoring, periodic healthy examinations and follow-up, and education because a significant proportion of staff has high and low frequency hearing loss.
