Soundproof walls are all products reducing the sound pressure with respect to a specified sound source and receptor.
Soundproof walls are to be made by considering the sound absorbing coefficient, transmission loss of sound, insertion loss of sound etc. Depending on used materi-al, soundproof walls are separated by sound absorption type and sound reflection type
01: Sound Absorption Type
Soundproof walls are all products reducing the sound pressure with respect toa specified sound source and receptor.
Soundproof walls are to be made by considering the sound absorbing coefficient, transmission loss of sound, insertion loss of sound etc. Depending on usedmaterial, soundproof walls are separated by sound absorption type and sound reflection type
It have grade 1 performance of NRC and offer fine view by a variety of colors and design. It prevent light reflection and corrosion by coating powder at front & rear plate. It is easy to maintain and inspect and improve satisfaction of residents.
- Length : 1,960~3,960 mm, Width : 500 mm, Thickness : 100 mm
- Polyester(32-60K), t=40~66mm (Repellent treated)
- Polyester(over 100K), t=10~30mm (Repellent treated)
Front Plate & Rear Plate
- Front Plate : Zinc steel plate, t=0.6~0.8mm
- Rear Plate : Zinc steel plate, t=1.6mm
02: Sound Reflection Type (Transparent)
This type is blocking out noise by sound reflection. It is very useful for securing a clear view. Soundproof panel consist of the main body and separating frame.So It is easy to change panels.
When the transparent plate is damaged. It is possible to replace the transparent plate by release frame. Easy to maintain and easy to clean.
So satisfaction of Residents are very high.
Mixed use : sound absorption type and reflection type, It is possible to upgrade aesthetic view and sound absorption performance.
- Length : 1,960~3,960 mm, Width : 500~1,000 mm, Thickness : 60~95 mm.
- Laminated glass or Poly methyl methacrylate.
- Aluminum alloy.
03: Noise Interference Device
It is very effective at the high noise-making area which is hard to reduce the noise.
It is possible to control noise by installation at the upper part of soundproof walls
It is controlled noise using interference principal and diffraction char-acteristic. Noise passing interference device conflict with noise passing upper soundproof wall for reducing noise.
It can gain the same soundproof effect as the existing soundproof wall even when the soundproof wall is designed by 2~3m lower.
It is economical because of reducing a footing /support size.
It can be harmonized with surrounding environment with its various colors.
- High noise-making area which is hard to reduce the noise with the simple soundproof facility
- Noise-making area restricted by height
- High bridge or structure (road or railway)
04: Soundproof Tunnel
When noise area is high-rise building or can’t install soundproof wall, must be regarded as the soundproof tunnel installation.
We need to examine about structural stability because It is important permanent structure.
We provide total service from Analysis noise reduction to Construction for economical and excellent soundproof tunnel.
When soundproof tunnel is installed on the bridge, need to consider to additional load and expansion joint.
