흡음형 방음벽은 소음원으로 부터 수음점(소음에 영향을 최대받는지점)까지 발생되는 소음을 감쇄시키고 방음벽에 부딪혀 나오는 반사음도 흡수하여 소음저감에 가장 뛰어난 방음벽. 1,960mm(L) X 500mm(H) X 95mm(W). 3,960mm(L) X 500mm(H) X 95mm(W). 방음벽의 투과손실은 10dB을 더한 값 이상으로 하거나, 500Hz의 음에서 25dB이상, 1000Hz의 음에 대하여 30dB 이상을 표준으로 한다. 투과손실 측정방법은 KS F 2808 따른다. 1/3 옥타브 밴드의 중심주파수 250Hz,500Hz,1000Hz,2000Hz 에서의 흡음률을 측정하여 그 산술 평균값이 0.7 이상이어야 한다. 흡음률 측정방법은 KS F 2805 따른다. 투과손실 : 소음에너지가 방음판을 투과하기 전과 투과한 후의 음압레벨 차이. 흡음률 : 입사음 강도에 대한 흡수음 강도의 백분율.

간섭통로로 들어오는 입사 소음의 파장을 1.5배 증가시켜 위상차가 반대인 파형으로 변조하여 배출함으로써 방음벽 상단 너머로 향하는 원 소음을 간섭, 저감할 수 있도록 고안한 장치. 간섭장치의 소음 저감 원리]. 간섭장치의 소음 저감 원리]. 방음벽의 높이를 약 2 4m 줄일 수 있으므로 매우 경제적임. 일반 방음벽으로는 매우 힘든 저주파 소음에 대한 저감이 높으므로 건물 고층부에 대한 저감효과가 매우 높음. 방음벽의 높이가 낮아지므로 풍하중에 대한 구조물의 안정성에 크게 기여. 기존 방음벽의 경우 높이를 증가하지 않고도 민원해결이 가능하므로 매우 경제적임. 반사 경로차에 의한 소음 소멸간섭. 통과 경로차에 의한 소음 소멸간섭. 회절음 흡수에 의한 흡음. 방음벽 지주에 연결하여 고정시킴. 방사형 split 알루미늄 프레임.
