Highway acoustic sound barrier panels are installed between the sound source and the recipient to have the function of sound reduction.
Acoustical barrier has excellent performance in acoustic and thermal insulation, as well as protection of highway traffic. acoustic sound barrier material classification:
metal sound barrier (metal louvers, metal mesh holes),
concrete sound barrier
PC sound barriers,
sound barriers, such as fiberglass.
The acoustic panels materials options:
Perforated metal mesh sheet;
metal louvers barrier;
Non metal panels (Vinyl, PC sheet);
Concrete sound barrier (lightweight concrete, high strength concrete).
The panels can be combined with acoustical foam, mineral fiber, glass fiber, etc.
metal and vinyl barrier can be used in soundproof walls, ceilings, industry, constraction, ome appliances, mechanical equipment, etc.
Acoustic Barrier Applications:
Highway Construction System
Common walls
Placed over drop-in ceiling systems
New construction/between studs.
Where ever Sound Transmission Control is needed.
