For the purpose of evaluationg the influence of noise exposure to the health a population, a cross sectional study was planned on the population of a district near an airport as the exposed group and the population of a provincial village as control group from August to October in 1988.
The results were as follows;
1) There was significant difference between two groups in frequency of complaints of hearing loss, tinnitus, ear fullness, tachycardia, tingling sensation, facial flushing, headache, nervousness, insomnia, anorexia, chest discomfort, dyspnea, edema.
2) There was significant difference between two groups in value of systolic blood pressure and diastolic blood pressure. But there was no significant difference in the prevalence of hypertension. 3) The degree of hearing loss according to the audible frequency was most notable in 4,000Hz.
4) There was significant differences between two groups in the degree of hearing loss at 500, 1,000, 2,000, 4,000Hz. on pure tone audiogram.
5) Age and exposure time and hearing loss were demonstrated as the variables of correlation.
6) The comparision of prevalence according to recognition methods for noise-induced hearing loss resulted in 22.7% as WHO method, 26% as 6-divided method, 22.7% as ELI applied method in exposed group.
