What is the sound barrier? What is the specific effect?
A sound barrier is a facility that blocks sound waves between the sound source and the receiver, thereby reducing the noise in the area where the receiver is located. According to the sound barrier application environment, the sound barrier can be divided into traffic noise barriers, equipment noise attenuation noise barriers, industrial plant noise barriers three.
At present, the market common sound barrier main material metal sound barrier, concrete sound barrier, PC sound barrier, glass steel sound barrier and so on. Metal sound barrier high cost, easy to rust; ordinary concrete from the major, low strength; PC sound barrier low hardness, poor UV resistance; FRP sound barrier cost is high, no fire.
Magnesium sound barrier is made of modified magnesite cement as the base material of the new sound barrier, the current magnesia sound barrier with its unique advantages have been widely used in roads, light rail, railway, culverts, tunnels and other transportation areas.
