산업장 소음 노출 근로자의 청력에 미치는 영향은 주로 순음청력검사를 통해 개인의 청력, 즉 역치변화를 감지한다. 순음청력검사는 소음성 난청의 발생 위험을 감소시킬 수 있 는 효과적인 선별검사 방법으로 진단, 사후관리, 보상 및 배상의 중요한 기준이 되며, 사업장에서는 근로자의 청력보 존프로그램의 성공 여부를 평가할 수 있는 지표가 된다. 순음청력검사에서 청력역치를 얻는 과정중 기계의 정확 성뿐만 아니라 검사실 환경, 검사자가 사용하는 기법, 그리 고 피검 근로자의 협조 등이 검사의 신뢰도에 영향을 주는 것으로 알려져 있다. 소음 특수건강진단에서 청력검사의 정확성(validity)과 신 뢰성(reliability)에 그동안 의문이 제기되었으며, 소음성 난 청의 판정과 관련한 청각도(오디오그램, audiogram) 상의 청력 평가의 문제점 및 기관간의 상이점 등에 있어서도 논 란이 있었다. 즉, 청력의 측정 및 평가에 있어서 이러한 문
The accuracy of audiomertric results of noise-exposed workers came out to the main issue on occupational health from late eighties. The discrepancy of the results for same person from different medical providers made the diagnosis for occupational diseases be unreliable. Pure-tone audiometric test can be influenced by technical as well as biological variables, and the quality control of test has been stressed as an important part of hearing conservation program. Therefore, the Korean audiometric quality control program for the special health examination was performed by the Industrial Safety and Health Research Institute in Korea, 1996. This study was conducted to evaluate the current status of audiometric testing program in workers’ health examination, and the variability of test results when quality control is not achieved. It was investigated the current status of facility, equipment, and man power of the organization of hearing measurement and then reviewed the quality control program to check the applicability to meet the development of quality control program. Audiometic quality control program about periodic special examination agencies and examiners will continue to be needed and also the evaluation of hearing loss should be performed and controlled using accurate criteria. This will reduce the error among examiners and results in individuals by means of a standard that is capable of being accurate and reliable.
