Noise Interference Device
Noise interference device is installed on top of soundproof wall to reduce noise using interference and diffraction principles of sound.
- Noise control principle of interference device
It is a sound reduction technology using the difference of diffraction. When sound penetrates an interference device, its sound directly enter on top of soundproof wall.
Sound Proof Tunnel
Soundproof tunnels are considered a representative way to perfectly prevent noise by minimizing the effect of diffracted sound taking place in the general areas of upper and lower parts in existing vertical soundproof walls.
Mold Production
Mold is a frame to produce segment and PC products (file, pole, culvert and block). We carry out design, manufacture and delivery according to segment and P.C. product shape.
Monorail
A monorail is a railway in which the track consists of a single rail. The term is also used to describe the beam of the system, or the vehicles traveling on such a beam or track.
