ENVIRONMENTALLY SOUND ABSORPTION SOUND INSULATION BOARD
The present invention relates to an environmentally friendly exhaust reduction sound absorption soundproof plate installed in an environment such as a roadside having a lot of noise and air pollution or an industrial area and, especially, a space having a large amount of ventilation. A sound absorption material made of polyester between a front plate having a plurality of inlet holes and a rear plate having a convex portion in the outside of the center. The interval retaining sound absorption materials made of the polyester are interposed at constant intervals between the inside of the rear plate and a rear portion of the sound absorption material. An air residence space unit is formed between the interval retaining sound absorption materials.
본 발명은 소음 및 대기오염이 많은 도로변이나 공업지대 등의 환경 특히, 통풍량이 많은 장소에 설치하는 친환경적 매연 저감 흡음 방음판에 관한 것이다. 본 발명은 다수의 흡입구멍이 형성된 전면판과 중앙 외측으로 볼록부가 형성된 후면판의 내부 사이에 폴리에스테르로 이루어진 흡음재를 설치하는 방음판에 있어서, 상기 후면판 내측과 흡음재 후면부 사이에 일정 간격으로 폴리에스테르로 이루어진 간격 유지용 흡음재를 개재하되, 상기 간격 유지용 흡음재와 간격 유지용 흡음재 사이에 공기 체류 공간부를 형성하여 구성함을 특징으로 한다.
