ABSTRACT
Objective:
To investigate the relationship between aircraft noise and the results of audiological evaluation on tinnitus and hearing loss among residents near United States military air-bases in Pyeongtaek city.METHODS:
Residents (n=492) exposed to aircraft noise were selected from eight villages near U.S. military air-bases (K-55 and K-6) in Pyeongtaek city. Residents (n=200) from five villages located at least 10 km away from the air-base were selected for the control group. All participants completed a questionnaire on tinnitus and audiological evaluations included pure tone audiometry (PTA) and distortion product otoacoustic emissions (DPOAE). Statistical analyses involved a general linear model and multiple logistic regression stratified by gender and data was adjusted by age, educational level, stress response index and noise type (i.e. military, agricultural and occupational).RESULTS:
The equivalent noise levels (Leq) in the vicinity of the air-field were 73.4~81.5 dB (A). Tinnitus prevalence was 47.3% and odds ratio (OR) was 2.06 (95% confidence interval (CI) 1.09~3.88) among noise-exposed males. Tinnitus prevalence was 50.8% and OR was 1.97(95% CI 1.17~3.30) among noise-exposed females. Tinnitus handicap scores among exposed group were significantly higher in functional, emotional, and catastrophic subclasses (p<0.001). PTA revealed hearing thresholds among the exposed group of 0.5 and 1 kHz (male right ear), 0.5 and 1 kHz (female left ear) and 0.5, 1, 2, 3, 4 and 6 kHz on female right ear that were significantly higher than those of the unexposed group. No significant difference in DPOAE was observed among noise-exposed males. However, significant differences were evident for noise-exposed females at 3175 and 4007 Hz. ORs of right female ears 3175 and 4007 Hz were 1.73(95% CI 1.01~2.99) and 1.78(95% CI 1.01~3.15). ORs of left female ears at 3175 Hz and 4007 Hz were 1.92(95% CI 1.10~3.36) and 2.71(95% CI 1.49~4.91)CONCLUSIONS:
Aircraft noise may adversely affect hearing function and tinnitus.
