SOUNDPROOFED WALL HAVING IMPROVED SOUNDPROOFING STRUCTURE AND INSTALLATION METHOD THEREOF

摘要

PURPOSE: A soundproofed wall having an improved soundproofing structure is provided to soundproof effectively by reducing the noise transferred to a space between a sound-absorbing part and a sound-insulating part and preventing noise from being transferred to the opposite side of noise sources. CONSTITUTION: The soundproofed wall having an improved soundproofing structure comprises: many columns(142) coupled to the upper part of a support and provided with a fixing part for fixing a case to the column(142) and a sound-insulating part containing a screw hole to form an air layer between a sound-absorbing part(110) and a sound-insulating part to remove noise; a sound absorbing part(110) coupled with the column(142) and provided with a case closed after interposing sound-absorbing materials and many holes to let noise flow in a case and transfer the noise into thermal energy by sound-absorbing materials to be set off; and a cover coupled to the upper part of the column(142).
