철도 방음벽 실내 시험 규격안에 대한 연구: 음향 성능 시험방법을 중심으로

초록

The number of railway noise barriers is increasing mainly in urban residential areas as a solution for civil complaints on railway noise. Detailed specifications for performance, test criteria, etc., for existing noise barriers tend to differ, and in South Korea, specific standardsfor performance tests for railway noise barriers have not yet been developed. As intensifying environmental standards are necessitatinghigh-performance noise barriers, and as the importance of noise barrier performance and management is increasing in accordance withnoise barriers’ lifespans, performance test standards for railway noise barriers will need to be thoroughly investigated. In this study, domesticand international performance standards were examined to develop effective indoor test standards for railway noise barriers for the SouthKorean railway system. BS EN 16272 was reviewed to develop indoor test methods for determining acoustic performance of noise barriersin a laboratory. We proposed test methods and criteria for transmission loss and sound absorption rates, and an installation method fornoise barrier specimens
