title: Hearing loss in Thai naval officers of coastal patrol crafts.
abstract: This cross-sectional study aimed to examine the prevalence of hearing loss and its risk factors among Thai naval officers. The subjects consisted of 149 males who were asked to complete a questionnaire. Audiometric threshold testing was performed at the audiometric frequencies of 0.5, 1, 2, 4, and 8 kHz. The noise levels and the organic solvent concentrations in the working environment were measured on a common type of gun boat. The findings revealed that 39.6% of naval officers had hearing loss. The noise level (LAeq) was 100.6 dB in the engine room. The organic solvent concentrations were less than the occupational exposure limit for organic solvents. Multiple logistic regression analysis indicated 2 factors were significantly associated with hearing loss. They were age and service experience. The results suggest that the Thai navy should develop a hearing conservation program for naval officers on coastal patrol crafts.
