Description
본 발명은 공연장,오락실 등의 실내벽에 부착되어 음향을 난반사시켜서 음향을 감쇄시킴과 동시에, 음향을 흡수할 수 있는 실내용 방음판에 관한 것이다.The present invention relates to an indoor soundproofing panel that is attached to an interior wall of a performance hall, an entertainment room, etc. to diffuse sound and attenuate the sound and to absorb the sound.
종래로부터 널리 사용되고 있는 방음판으로서는 한국 실용신안공보 제1818호의 공고번호 제93-6163호가 있다. 동 공보에 개시되어 방음판은 도 1에 도시한 바와 같이 무수한 연쇄기공이 균일한 분포로 형성된 폼크리트를 흡음판(1)으로 하고 혈암을 1,200℃로 가열 부풀린 독립성 기공으로 된 무기질 다공성 골재와 금강사 및 쇼트스틸 등을 시멘트 몰타르에 혼합하여 제조한 차음판(2)을 상기 흡음판(1)과 스페이서(3)에 의하여 작은 간극(4)을 두고 이중으로 집합형성하여 흡음판(1)의 전면에 엉글게 된 섬유포지(5)를 대고 다수의 흡음공(6)이 형성된 알루미늄케이스(7)를 씌워 차음판(2) 뒷면만이 노출된 방음판(8)을 구비하고 있다.As a sound insulation board widely used in the past, there is a publication number 93-6163 of Korean Utility Model Publication No. 1818. As shown in FIG. 1, the soundproof plate is an inorganic porous aggregate made of independant pores in which foamcrete formed with a uniform distribution of innumerable chain pores as a sound absorbing plate 1, and shale is heated to 1,200 ° C. The sound insulation plate 2 manufactured by mixing steel or the like with cement mortar is formed into a double space with a small gap 4 by the sound absorbing plate 1 and the spacer 3 to be entangled in front of the sound absorbing plate 1. The sound absorbing plate 8 which covers the back of the sound insulation board 2 is covered with the aluminum case 7 in which the plurality of sound-absorbing holes 6 were formed on the fiber cloth 5.
이와 같이 구성된 종래의 방음판은 도시하지 않은 지주 사이에 흡음공(6)이 소음원을 향하도록 상하 일정한 높이로 방음판(8)을 시공하여 도로를 주행하는 차량 등 각종 소음을 케이스(7)의 흡음공(6)을 통하여 투사된 다음, 포지(5)에 의하여 1차적으로 약화되고 있어 흡음판(1)의 무수한 연쇄기공내로 들어 가면서 반복되는 무수한 공명진동에 의한 심한 공기 마찰 저항에 의하여 소음에너지는 열에너지로 변환되어 공명소음 이론에 따라 소음된다.In the conventional soundproof board configured as described above, the sound absorbing hole of the case 7 is installed in the sound absorbing plate 8 at a predetermined height so that the sound absorbing hole 6 faces the noise source between the props not shown. The noise energy is projected through (6), and then weakened primarily by the forge (5) and enters into the myriad of chain pores of the sound absorbing plate (1). The noise is converted and resonated according to the theory of resonance noise.
또한 일부 나머지의 소음에너지는 흡음판(1)과 차음판(2) 사이의 간극(4)의 공기층에 의하여 더욱 악화된 다음, 차음판(2)에 의하여 반사되어 간극(4)과 흡음판(1)내에서 반복되는 공명소음 작용에 의하여 모두 소실되어 방음할 수 있다.In addition, some of the remaining noise energy is further deteriorated by the air layer of the gap 4 between the sound absorbing plate 1 and the sound insulating plate 2, and then reflected by the sound insulating plate 2 so that the gap 4 and the sound absorbing plate 1 are provided. All of the sound is lost by the repetitive resonance noise in the room.
그런데, 이와 같이 구성된 종래의 방음판은 도로의 양쪽에 세로로 설치된 지주에 설치되어 차량에서 발생되는 소음을 방음함과 동시에, 차량의 주행에 따라 튀는 자갈 등이 튀어 방음판에 부딪쳐도 케이스와 포지에 의하여 흡음판의 표면을 안전하게 보호할 수 있기는 하나, 지주사이에 설치하여야 하므로, 설치비용이 많이 소요될 뿐만 아니라 무거워서 설내의 소음용 방음판넬로는 사용할 수 없다는 문제점이 있다.However, the conventional sound insulation board configured as described above is installed on vertical posts installed on both sides of the road to soundproof the noise generated by the vehicle, and at the same time, the sound absorbing plate is prevented by the case and the forge even when splashing gravel or the like splashes as the vehicle travels. Although it is possible to protect the surface of the safe, because it must be installed between the struts, not only takes a lot of installation cost but also has a problem that can not be used as a soundproof panel for noise in the snow.
