The sound wave is introduced into the resonance space 132 disposed at the front along the sound absorbing hole 112 formed in the front sound absorbing plate 110 (see FIG. 2), and is exhausted while being resonated to some extent, followed by the second and third resonance spaces. As it flows into (132) one by one, it continues to resonate and is exhausted.

이때, 전면흡음판(110)에 형성된 흡음공(112)과 첫 번째 구획판(140) 및 두 번째와 세 번째 구획판(140)에 형성된 유도공(142)의 크기와 배열형태가 서로 상이하게 형성되어 있음에 따라 음파는 일직선으로 진행하지 못하고 수차례 방향이 바뀌고 부딪혀 반사되면서 진행을 하게 된다. 따라서 서로 상쇄되면서 소진되어 흡음성능을 향상을 꾀할 수 있게 된다.At this time, the size and arrangement of the sound absorbing hole 112 formed in the front sound absorbing plate 110 and the first partition plate 140 and the guide hole 142 formed in the second and third partition plates 140 are formed different from each other. As a result, sound waves do not proceed in a straight line, but change direction several times. Therefore, it is exhausted while offsetting each other to improve the sound absorption performance.

한편, 마지막에 배치된 공명공간(132)에서는 반사유도판(120)에 형성된 반사돌기(122)에 의해 유입된 음파가 반사되면서 진입하는 음파를 상쇄시키는 작용이 더욱 활발하게 하게 이루어 지게 한다.
On the other hand, in the resonant space 132 disposed at the end, the effect of canceling the sound wave entering while the sound wave introduced by the reflection protrusion 122 formed in the reflection induction plate 120 is made to be more active.

이하, 본 발명에 의한 흡음블록(100)을 이용해 방음판넬을 형성하는 구조를 살펴본다. Hereinafter, the structure of forming the soundproof panel using the sound absorbing block 100 according to the present invention will be described.

도 10, 11은 본 발명에 의한 흡음블럭으로 방음판넬을 형성하는 것을 보여주는 예시도 이다.10 and 11 are exemplary views showing the formation of a soundproof panel with a sound absorbing block according to the present invention.

본 발명에 의한 흡음블록(100)은 다양한 형태로 형성하는 것이 가능하나, 지주 사이에 끼워서 설치하는 방음판넬을 구성하기 위해서는 사각형 형태로 형성하는 것이 바람직하다. 이를 통해 다수 개의 흡음블록(100)을 마련하여 사각 형태를 이루게 배열하여 조립함으로써 방음판넬로 형성할 수 있는 것이다.Sound absorbing block 100 according to the present invention can be formed in a variety of forms, in order to form a soundproof panel to be installed between the struts is preferably formed in a rectangular form. Through this, a plurality of sound absorbing blocks 100 may be provided and arranged to form a square shape to form a soundproof panel.

상기 흡음블록(100)의 조립은 조립틀(200)을 통해 달성할 수 있다. 흡음블록(100) 다수개를 일렬로 배열한 다음 상기 조립틀(200)을 배열된 흡음블록(100) 가장자리에서 사각 틀을 이루게 고정함으로써 방음판넬을 형성하는 것이다. Assembly of the sound absorbing block 100 may be achieved through the assembly frame 200. After arranging a plurality of sound absorbing blocks 100 in a row, the sound absorbing panel is formed by fixing the assembly frame 200 in a rectangular frame at the edges of the arranged sound absorbing blocks 100.

상기와 같이 방음판넬이 형성됨에 따라 흡음블록(100)의 개수를 조절함으로써 방음판넬의 좌/우 폭을 조절하여 줄 수 있다. 이때, 방음판넬의 개수가 너무 많으면 구성이 미세하게 되어 바람직하지 않은바, 통상적으로 3~5개를 이어서 방음판넬을 형성할 수 있도록 흡음블록(100)의 규격을 정하는 것이 바람직하다. As the soundproof panel is formed as described above, the left / right width of the soundproof panel may be adjusted by adjusting the number of sound absorbing blocks 100. At this time, if the number of sound insulation panels is too large, the configuration becomes fine, which is undesirable. Typically, it is preferable to determine the size of the sound absorbing block 100 so as to form the sound insulation panel following three to five.
