Railway Sound Barrier Sound Barrier: The sound barrier of the application environment, sound barrier into traffic noise barriers, noise reduction equipment noise barriers, industrial plant boundary noise barriers. Outdoor sound barrier generally use brick or concrete structures, interior sound barrier cited steel, wood, PMMA / POLYCARBONATE SHEET pull plastic, plasterboard and aluminum foam structure. 2.5 meters wide PC board to the Wuxi is a research and development success. Greatly improving light effect, enhance shock resistance! ! Resistance to weak acid and neutral oil. Effective use of up to 20 years. Railway noise barrier consists of two parts of steel columns and suction insulation panel composed of columns is the main force component sound barrier, which is fixed by bolts or welding on a road side barrier wall or rail embedded steel; suction compartment sound acoustic absorption panels are the main component, it is through high-strength spring clips to secure the H-type column groove formed sound barrier. Sound barrier design has been more fully into account the elevated highway, crash safety urban light rail, subway wind load, transport vehicles and all-weather outdoor corrosion problems. It is nice shape, producing exquisite, easy to transport, installation, low cost, long life, especially for the elevated highway and urban light rail, subway noise prevention use, is a modern urban best acoustic noise reduction facilities. Railway Noise barrier height in a 5m 1m between, cover the effective area of ??the average noise 10 ~ 15dB (A) (125Hz ~ 40000Hz, 1/3-octave), up to 20dB (A). In general, the higher the sound barrier, or farther away from the sound barrier, the noise reduction, the better
