What is a "sound barrier" on a highway? Are there any other ways to reduce noise on the highway? Sound barriers, also known as noise barriers or noise walls, are usually installed on highways that pass through villages. Because of the high speed of highway vehicles, there is a lot of noise, firstly, air friction, secondly, engine noise, thirdly, tyre friction with the ground, and fourthly, the horn of the car. To reduce the noise, you can plant trees, improve the model of the car, improve the structure of the road surface. There are also measures to reduce road noise interference such as installing soundproof windows on windows at home and using low-noise asphalt surfaces for roads.

Waveform guardrail utility model involves a highway central divider opening with a combination of waveform plate movable steel guardrail, the guardrail consists of two pieces of waveform steel guardrail plate and the two fixed between the two clamped two columns, two columns fixed clamped between the two pieces of waveform steel guardrail plate. In the normal operation of the highway, the guardrail using the insertion and extraction of columns can be easily inserted into the opening of the pre-set insertion and extraction of holes, play a role in isolation and protection, while echoing with the highway on the outside edge of the guardrail belt, neat and tidy, beautiful supporting. Vehicle collision, due to the waveform steel guardrail plate has a good crash resistance and energy absorption effect, neither easy to be crashed, with the same
