최근까지 경제발전과 산업화·기계화로 고소음을 발생하는 사업장이 증가하고 있는 추세이다. 세계보건기구(WHO)에서는 성인에서 유발되는 소음성 청력손실은 개인의 사회적 고립에서 많은 국가적 경제부담까지 심각한 영향을 끼칠 수 있는‘15번째로 가장 심각한 건강문제’라고 말하고 있다.14) 국내에서는 작업환경 중 소음은 1995~2000년의 조사에서 소음의 노출기준 초과율이 1995년의 39.7%에서 2000년의 26.5%로 감소추세에 있으나 유해인자 중 가장 높은 초과율로 나타났다.1) 따라서 고소음 사업장에서 고소음 기계로 인한 소음피해는 행정적, 기술적 저감대책이 필
High level noise at workplace results in noise-induced hearing loss (NIHL). It was determined by World Healthe Organization (WHO) that the NIHL be the most fifteenth most serious problem found in adults and could derive individual social isolation and national economic burden. Domestic workplace noise also have been increased showing the highest exceeding rate out of several harmful factors during 1995-2000. NIHL, tinnitus and various other problems. It is necessary to equip various adminstration programs for preserving worker’s health from high level noise at workplace. The purpose of this study was to propose an tentative plan of domestic noise labeling and noise control application model. After searching the advanced country’s noise labeling system, actual condition of noise existence at workplace, and noise control system for the working environment and the noise generating instruments, the following two methods were proposed. One was a tentative plan of domestic noise labeling indicating noise quantification of frequency weighting, the rate of noise generation including the range of noise level, and diagrammed spectrum of the noise. The other was noise control application model that can measure the noise at the real working place, analyze the characteristics of noise, and developing the noise managing program with finding and controling noise causing instruments, effective noise measuring steps, and hearing conservation program. We can expect better working place with the successful noise labeling and controling system. KEY WORDS：Noise labeling·Noise control·High noise level·Hearing conservation program
