델파이 조사를 통한 직업적 소음 노출 규모의 추정

Abstract

Objective: The objective of this study was to estimate the numbers of employees occupationally exposed to noise according to their industry and size.

Methods: A Delphi panel consisting of 15 occupational health experts estimated the exposure prevalence of noise in workplace. Data on Industrial Accident Compensation Insurance provided from Occupational Safety and Health Research Institute were combined to produce the exposure population.

Results: In Korea, 16.0% of employees, 2,539,890 out of 15,838,926, was estimated to exposed to noise occupationally. The rate was 32.7% and 10.3% in manufacturing sector and non-manufacturing sector, respectively. The highest rate, 52.5%, was found in manufacturing industries of wood and of products of wood and cork(except furniture) and of other transport equipment. Sorted by their size of business, the rate was higher as the number of employee was larger in manufacturing sector.

Conclusions: Compared to the same rate estimated in the US, 17.2%, the result of this study seems to be in a resonable range.
