The present invention relates to a mixed soundproof wall, and more particularly, to a soundproof wall having a soundproof decorative material installed on the surface of the soundproof wall, thereby improving the soundproofing effect and improving the aesthetics of the exterior.

Hyundai is enjoying civilization through the development of transportation, especially automobiles and trains.However, as a side effect, the noise generated by such transportation causes serious environmental pollution due to the increase of the number of vehicles and the increase of the number of driving. It is increasing every year. As a countermeasure for noise reduction, a method of reducing a traffic means, which is a noise source itself, and blocking a path of noise issued therefrom may be proposed, and a noise barrier is a representative example of the noise reduction means.

The soundproof wall is a wall installed to block the sound waves with a wide wall to reduce the size of the sound transmitted to the back of the wall. The soundproof wall is mainly installed between the paths for the transmission of the noise. Since the generated noise is transmitted over the sound barrier, it can be divided into bypass sound, transmission sound, and ground reflection sound. The soundproof walls can be divided into reflection type and sound absorption type according to the material of the soundproof panel. The reflection type is made of a solid material such as concrete, wood, polycarbonate, and the sound absorbing type is a case of using a flaw material behind the aluminum porous plate. If the basic characteristics (transmission loss, sound absorption rate) for the sound barriers are satisfied, the effect on the receiver is the effect of diffraction sound to the upper end of the sound barrier.

Controlling the effect of the diffraction sound can be evaluated as the difference in sound pressure level before and after the soundproof wall installation, that is, insertion loss, and the larger the insertion loss, the more effective soundproof wall is. The main focus of this development is to increase the height of the soundproof wall to extend the transmission distance of the diffraction sound. The method of increasing the soundproof wall thickness and the method of changing the shape of an upper end part are proposed. Increasing the height of the soundproof wall may be the most effective, but the visible area may be limited, so a number of methods for changing the shape of the upper end or improving the sound absorbing material have been proposed.
