POROUS PANEL FOR REDUCING NOISE AND MANUFACTURING METHOD THEREOF
Disclosed is a noise-reducing porous panel. The noise-reducing porous panel of the present invention comprises: a first porous panel unit with a plurality of first through-hole units through which air flows; a second porous panel unit arranged to face the first porous panel, having a plurality of second through-hole units at positions corresponding to the first through-hole units; and noise-reducing panel units connected between the first and second porous panel units, having noise-absorbing pipe units forming air passages radially formed around the first and second through-hole units. The purpose of the present invention is to provide the noise-reducing porous panel capable of effectively reducing noise at a specific frequency band, and a manufacturing method thereof.
소음 감쇄용 다공성 패널에 대한 발명이 개시된다. 본 발명의 소음 감쇄용 다공성 패널은: 공기가 통과할 수 있는 복수개의 제1통공부가 형성되는 제1다공패널부와, 제1다공패널부와 대향되게 배치되고, 제1통공부에 대응되는 위치에 복수개의 제2통공부가 형성되는 제2다공패널부와, 제1다공패널부와 제2다공패널부의 사이에 결합되고, 제1통공부와 제2통공부를 중심으로 방사형의 공기 통로를 이루는 흡음관부가 형성되는 소음감쇄패널부를 포함하는 것을 특징으로 한다.
