An object of the present invention is to provide a method of manufacturing a sound-absorbing board using honeycomb, and a sound-absorbing board using honeycomb, manufactured by using the same, characterized in that when designing a sound-absorbing board manufactured by laminating a glass fiber mat on each side of a honeycomb structure that is lightweight and has structural rigidity and foaming polyurethane, a sound absorption coefficient is calculated using diameters of perforations, the number of the perforations and porosity thereof, wherein the sound-absorbing board is designed in a way that perforations with diameters that have sound-absorbing effect in a predetermined frequency band are formed in the polyurethane, and accordingly, sound absorption performance in the predetermined frequency band can be further increased and it is possible to reduce the weight of the sound-absorbing board by making the sound-absorbing board thin.

    본 발명은 가벼우면서도 구조적 강성을 갖는 허니컴 구조의 양쪽에 각각 유리섬유 매트를 적층하고 폴리우레탄을 발포하여 제조하는 흡음 보드를 설계할 때, 천공의 지름과 개수 그리고 기공률을 이용하여 흡음률을 계산하되 미리 정한 주파수 대역에서 흡음 효과가 있는 지름의 천공을 폴리우레탄에 형성할 수 있게 설계함으로써, 미리 정한 주파수 대역에서의 흡음성능을 한층 더 높일 수 있을 뿐만 아니라 흡음 보드의 두께를 얇게 제작하여 중량을 줄일 수 있게 한 허니컴을 이용한 흡음 보드의 제조 방법 및 이를 이용한 허니컴을 이용한 흡음 보드를 제공하는데 그 목적이 있다.
