Purpose: The purpose of this study was to investigate the characteristics of hearing loss or tinnitus in a Korean military hospital.
Methods: The subjects were 123 military officers and enlisted soldiers who had received treatment for hearing loss or tinnitus from May, 2014 to April, 2015. Data were collected using a 12 items questionnaire and pure-tone audiometry measurement. The authors conducted descriptive statistics, χ²-test, t-test, and ANOVA.
Results: The main cause of hearing loss and tinnitus was shooting drills (56.1%), followed by unknown (23.6%) and noisy work environment (20.3%). 30.9% of the subjects reported that they used hearing protection equipment, 40.7% received hearing protection education, and 66.7% knew how to correctly use earplugs. Their symptoms included tinnitus (89.4%), difficulty in hearing (70.7%), ear-fullness (61.0%), and dizziness(11.4%). According to the ISO(1964) standards, the degree of hearing loss was 23.7% and 17.7% for left and right ear, respectively. Age, rank, and hearing loss were found to significantly affected hearing threshold.
Conclusion: Military health workers need to standardize the preventive measures to effectively protect hearing of military personnel. The standard should include identification of causes of hearing loss, education on hearing protection, such as a correct use of protection devices, assessment of symptoms, and regular hearing check-ups.
