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.
