The present invention relates to a wooden soundproofing wall with improved noise blocking properties. A hanging groove is formed on the rear surface of each rear plates, and a connection bracket is connected to the adjacent hanging groove. Therefore, the present invention minimizes deformation and blocks noises by preventing a gap from being generated. A sound insulation plate is installed between a sound absorption plate and the rear plate, and a space unit (air layer) is formed by being individually separated from the sound absorption plate and the rear plate. Therefore, the present invention can improve sound absorption properties and sound insulation properties. The sound insulation plate is one integrated structure so that it can improve the sound insulation properties and prevent the sound from being leaked due to the gap. |
