Supply Hao Feng bump bump-type sound barrier type noise walls are available upon request

The sound barrier of the application environment, sound barrier into traffic noise barriers, noise barriers noise reduction equipment, industrial plant boundary noise barriers. Sound Barrier Material classification can be divided into the following categories: metal sound barrier (metal blinds, metal mesh hole), concrete sound barrier (lightweight concrete, high strength concrete), PC sound barrier, fiberglass sound barriers. 2.7 meters wide, the widest pc plexiglass plate steel production in Wuxi has been positive to the sound barrier plant installation is successful, greatly improve the visual and noise effects according to different uses it can be divided into several categories: railway barrier, highway sound barriers, city Landscape sound barrier, reducing noise barriers and other irregularities residential perforation sound barrier material: galvanized steel, aluminum, color steel, iron, and other metal plate thickness: 0.6mm, 0.7mm, 0.8mm, 1.0mm (according to customer requirements) forming thickness: 80cm, 100cm, etc. (can be customized according to customer requirements) Pass: Distance frequency, barrier height and the sound source and the receiving point of the hole punch bump noise sound barrier between the amount of noise, etc. factors. A large component of the relationship between metal sound barrier noise reduction and noise frequency of greater than 2000Hz frequency acoustic noise reduction ratio of about 800 to 1000Hz intermediate frequency sound better, but around 25Hz low-frequency sound. Due to relatively long wavelength acoustic and easily diffracted from the barrier above the past, so the effect is poor. Generally, a metal sound barrier to reduce high-frequency sound l0-15dB. Highly uneven perforation sound barrier, according to the design height doubling of distance from the sound source and the receiving point, the metal barrier, then the noise increase the amount of 6dB, in order to make the metal barrier noise better, should be metal barrier close to the sound source or receiving point. .
