As is well known, sound barriers are walls that are thickened or made of soundproof material to block outside noise or room acoustics from being transmitted elsewhere, so that sound waves can be blocked by a wide wall to reduce the volume of sound transmitted behind the wall. Is installed.

Such soundproof walls are mainly installed for the purpose of blocking noise, and are installed between the place where the noise is heard from the place where the noise occurs, and a large soundproof wall installed beside the road is typical. Since the sound is transmitted in the form of waves, the soundproof wall is made in consideration of the law of motion of the wave. Therefore, it is common to make the height high or make the thickness thick. It is also manufactured using special sound-proof materials that can absorb sound waves.

These soundproof walls are manufactured in consideration of the 'sound point', which is the location that receives the most noise, and at the time of production, the sound absorption rate of how much sound can be absorbed and the permeation of how much noise passing through the wall is reduced. Loss, and the insertion loss, such as how much the decibel value after the installation of the soundproof wall is considered. In Korea, the soundproof wall is manufactured or installed according to the standards announced by the Ministry of Environment, and recently, not only the functional aspect but also the aesthetic or safety aspect are considered.
