Road Noise Barrier Green Transparency Sound Barriers Fence Wall Fence

In order to block the direct sound between the sound source and the receiver, it inserts a

facility between the sound source and the receiver, so that there is a significant additional

attenuation of the sound wave propagation, thus reducing the influence of the noise in a

certain area of the receiver.

Acoustic barriers are mainly used outdoors. Along with the road traffic noise pollution becomes

more and more serious, some countries adopt various kinds of barriers to reduce the traffic noise.

In a building, a barrier can also be used to separate the workshop from the office if sound

insulation is not required. The barrier is more convenient to disassemble and move, and has

certain sound insulation effect, so it is widely used.

Between the sound source and the receiving point, a solid material wall or wall with sufficient

surface density is inserted vertically to cause a significant additional attenuation of the sound

wave in transmission. Such an "obstacle" is called the sound barrier.
