Disclosed is a sound absorbing sound insulation board. The disclosed sound absorbing sound insulation board comprises: a front surface frame having a plurality of through holes on the front surface; a rear surface frame provided at a position opposite to the front surface frame; a side wall unit connecting the front surface frame and the rear surface frame; a plurality of first sound absorbing members disposed adjacent to the front surface frame and absorbing a first frequency region; a single second sound absorbing member disposed behind the plurality of first sound absorbing members and absorbing a second frequency region; and a honeycomb member disposed between the second sound absorbing member and the rear surface frame and forming a sound absorbing space between the second sound absorbing member and the rear surface frame. The first frequency region may be smaller than the second frequency region. An objective of the present disclosure is to provide the sound absorbing sound insulation board having improved sound absorption efficiency, assemblability, and drainage stability for various wavelength regions.
흡음형 방음판이 개시된다. 개시된 흡음형 방음판은 전면에 복수의 통공을 가지는 전면 프레임, 전면 프레임과 대향되는 위치에 구비된 후면 프레임, 전면 프레임과 후면 프레임을 연결하는 측벽부, 전면 프레임에 인접하게 배치되어 제1 주파수 영역을 흡수하는 복수의 제1 흡음부재, 복수의 제1 흡음부재 후방에 배치되어 제2 주파수 영역을 흡수하는 단일의 제2 흡음부재 및 제2 흡음부재와 후면 프레임 사이에 배치되어 제2 흡음부재와 후면 프레임 사이의 흡음공간을 형성하는 허니컴부재를 포함하고, 제1 주파수 영역은 상기 제2 주파수 영역보다 작을 수 있다.
