The present invention relates to a sound absorption board. A plurality of porous sound absorption plates (120) having a plate shape and including a protrusion (122) and a groove (124) which are formed on at least one side with regular patterns are provided to be stacked as a protrusion (122) formed on one of the sound absorption plates (120) is placed towards another sound absorption plate (120). Meanwhile, a punching plate (160) in which sound absorption holes (162) are punched with regular patterns is placed between the stacked sound absorption plates (120) to enable a sound wave that has passed through a sound absorption plate (120) at one side to be absorbed via an air layer formed by the groove (124) during a procedure in which the sound wave is getting exhausted while moving to a sound absorption plate (120) at the other side through the sound absorption holes (162) formed on the punching plate (160).
본 발명은 흡음보드에 관한 것으로, 판 형상을 이루어 적어도 일면에 돌기(122)와 홈(124)이 일정한 패턴으로 형성되는 다공질 흡음판(120)이 복수 구비되어 어느 하나의 흡음판(120)에 형성된 돌기(122)가 다른 흡음판(120)을 향해 배치되며 적층되되, 일정한 패턴으로 흡음공(162)이 천공되어 있는 타공판(160)이 상기 적층되는 흡음판(120) 사이에 배치되어 일측 흡음판(120)을 통과한 음파가 상기 타공판(160)에 형성된 흡음공(162)을 통과해 타측 흡음판(120)으로 진행하며 소진되는 과정에서 상기 홈(124)에 의해 형성된 공기층을 지나며 흡음 되는 흡음보드에 관한 것이다.
