   Road Noise Reduction Fence 

The material of the metal sound barrier: galvanized sheet, aluminum sheet, color steel sheet, iron sheet, etc. The thickness of the metal plate: 0.6mm, 0.7mm, 0.8mm, 1.0mm (can be customized according to customer requirements) Forming thickness: 50cm, 60cm, 80cm, 100cm, etc. (can be customized according to customer requirements) You can customize the color according to the drawing requirements

Highway noise barriers, the amount of noise reduction of highway noise barriers is related to factors such as the frequency of noise, the height of the barrier, and the distance between the sound source and the receiving point. The noise reduction effect of metal sound barriers is closely related to the frequency components of the noise. The noise reduction effect for high-frequency sounds greater than 2000Hz is better than that for mid-frequency sounds around 800-1000Hz, but for low-frequency sounds around 25Hz. Since the sound wave has a relatively long wavelength and is easily diffracted from above the barrier, the effect is poor. Generally, metal sound barriers can reduce high-frequency sound by l0-15dB. The height of the metal sound barrier can be designed according to the distance between the sound source and the receiving point. If the height of the metal sound barrier is doubled, the noise reduction can be increased by 6dB. In order to make the metal sound barrier have a better noise reduction effect, it should be Try to keep the metal barrier close to the sound source or receiving point.

The main features of the sound-absorbing board: 

1. Large sound insulation: tested according to GBJ75-1984, GB/T19889.3-2005, average sound insulation 37dB(A)~43 dB(A).

9. Bending and fracture resistance: qualified according to GB/T9341-2008. 

10. Waterproof and dustproof, beautiful and economical, advanced structure, easy to update.

The sound-absorbing and sound-absorbing panels are mainly composed of two parts: a steel structure column and a sound-absorbing and sound-proof screen. The column is the main stress member of the sound barrier. It is fixed on the road anti-collision wall or the embedded steel plate beside the track by bolts or welding; The sound board is the main sound-proof and sound-absorbing component. It is fixed in the H-shaped column slot by high-strength spring clips to form a sound barrier. Noise barriers are mainly used in high-speed railways, highways, viaducts, rail transit, power stations, hospitals, schools, industrial enterprise construction sites and other noise reduction products for acoustic environmental noise control.
