For the noise reduction measures in a construction field or near the traffic line receiver is often the most economic measure in order to exclude the propagated sound. The dimension of the barrier is decided by the noise and construction design, and the constructive quality of a soundproof panel shall be secured in accordance with KS F4770 to guarantee the safety of sound barriers. In this paper the problems included in the KS F4770-1 that is the regulation for the metallic sound barrier of the absorption type are identified and it is suggested what to be corrected or improved. Through a series of the analyses, conclusions were reached that it is required to improve test methods in KS F4770-1 as well as to break down test loads for building more cost-effective sound barrier.

발파, 항타와 같은 소원음이 존재하는 건설현장에서의 소음저감대책으로는, 소음원 또는 수음점에 방음벽을 설치하여 전파되는 소음을 차단하는 것이 가장 경제적인 경우가 대부분이다. 이러한 방음벽은 소음설계와 구조설계를 통해 그 규모가 결정되며, 방음벽의 구조적 안전을 보장하기 위해서는 KS F4770에 의한 방음판의 구조적 품질이 보장되어야 한다. 본 논문에서는 이 중 금속재 흡음형 방음벽 관련 규정인 F4770-1 - 2001을 분석하여, 그 문제점을 지적하고, 수정 또는 개선 사항을 제시하였다. 분석결과, 보다 경제적인 방음벽의 설치를 위하여 하중의 세분화와 함께 시험방법의 개선이 필요한 것으로 나타났다. 이와 함께 독일의 방음벽 설계시 사용되는 규정인 ZTV-Lsw 88과 비교, 검토하였으며, 검토 결과, 한국 규정은 독일규정에 비해, 보수적인 것으로 나타났다.
