PURPOSE: An environmentally-friendly soundproofing device is provided to include excellent soundproofing efficiency and shock absorbing efficiency and to prevent environmental contamination due to construction. CONSTITUTION: An environmentally-friendly soundproofing device comprises a soundproofing block(10), a soundproofing door(30), and a sound insulating layer(40). The soundproofing block is vertically loaded inside a tunnel(100) to block a passage and comprises a case, a sound absorbing member(S), and a net body. The sound absorbing member absorbs noise by injecting porous plant stems. The sound insulating layer is weaved with the plant stems and is vertically installed inside a tunnel of the soundproofing block. A blind(34) is automatically opened by a shock wave and absorbs noise to prevent damage to the soundproofing door. |
