Absorption-Insulation type wood soundproofing panel and soundproofing wall having the same
The present invention relates to a sound-absorbing and -insulating wood soundproof plate and a soundproof wall having the same laminated on each other, including: a sound-insulating plate of a rectangular transparent material; a left frame coupled to a left side of the sound-insulating plate and having a noise introduction passage formed therein in a longitudinal direction thereof; a right frame coupled to a right side of the sound-insulating plate and having a noise introduction passage formed therein in a longitudinal direction thereof; an upper frame coupled to an upper side of the sound-insulating plate and having a sound-absorbing passage formed therein in a longitudinal direction thereof; and a lower frame coupled to a lower side of the sound-insulating plate and having a sound-absorbing passage formed in a longitudinal direction thereof, wherein an inner surface of the sound-absorbing passage is brushed such that a lot of fluffs are generated, and the noise introduced into the sound-absorbing passage is reduced due to viscous friction with air as a lot of fluffs are vibrated and diffused.
흡차음형 목재 방음판 및 그것이 적층된 방음벽에 관한 것으로, 사각판 형태의 투명 재질의 차음판, 차음판의 좌측에 결합되고 내부에 길이방향으로 소음유입통로가 형성된 좌측프레임, 차음판의 우측에 결합되고 내부에 길이방향으로 소음유입통로가 형성된 우측프레임, 차음판의 상측에 결합되고 내부에 길이방향으로 흡음통로가 형성된 상측프레임, 차음판의 하측에 결합되고 내부에 길이방향으로 흡음통로가 형성된 하측프레임을 포함하고, 흡음통로의 내면은 다수의 보풀이 일어나도록 브러싱 처리되어 흡음통로로 유입되는 소음이 다수의 보풀이 진동하고 난반사되며 공기와의 점성마찰로 인해 감소된다.
