Abstract

이 연구에서는 고속도로 신설 공사 건설 현장 근로자들의 소음 노출을 저감할 수 있는 방법들을 제시하며 특히 현장에서 적용할 수 있는 새로운 체계적인 방법인 "소음 주의 구역"을 제안한다. 고속도로 건설 현장에서 소음원이 되는 장비, 기계, 도구와 근로자들의 소음 노출 특성을 알아 보았으며, 개인청력 보호구, 공학적제어수단 (engineering controls), 관리적제어수단 (administrative controls)을 어떻게 적용할 것인가를 제시하였다. 개인청력 보호구만으로는 소음 노출을 효율적으로 저감시킬 수 없음을 보였으며, 공학적제어수단은 기술적 및 경제적 문제로, 관리적제어수단은 공사 기간 단축과 같은 실제적인 이유로 해서 시행 되기가 어렵다. 따라서 이 연구에서는 실제적으로 적용할 수 있는 체계적인 방법으로서 "소음주의구역 (Noise Perimeter Zones)"을 새롭게 제안하였다. 이 "소음주의구역"은 높은 수준의 소음원이 존재하는 고속도로 건설 공사 현장에 지정된다. 이 구역안에서는 근로자들의 출입이 통제되며 또한 개인청력 보호구, 공학적제어수단, 관리적제어수단과 같은 적절한 제어수단이 사용되어야 한다.
