How much is the highway noise barrier per square meter?

There are many kinds of sound barriers, which can be roughly divided into metal, nonmetal and transparent sound barriers. Generally speaking, the price of sound barriers ranges from 200 yuan to 600 yuan per square meter; The specific price needs to refer to the material, specification, installation height, plate thickness, column size and other factors of the sound barrier.

There are two kinds of sound-absorbing materials used to isolate noise: pure sound barrier and composite sound barrier combining sound absorption and sound insulation, among which composite sound barrier is widely used.

The appearance of composite sound barrier is similar to that of pure sound insulation sound barrier, which is generally a metal sound barrier, a transparent sound barrier or a metal transparent combination sound barrier. Metal sound barriers are usually colored steel plates, aluminum plates, galvanized plates, etc. The transparent sound barrier is usually a pc board, and the price of different materials is different. There are sound-absorbing materials inside the composite sound barrier, mostly glass wool, and there are also good and bad points. Some even choose inferior materials instead of glass wool, which is naturally cheap, but the noise isolation effect is not great.

There are many kinds of sound barriers, both linear and curved, which is also the reason that determines the price of sound barriers. When choosing a suitable sound barrier, it is necessary to investigate the application environment of the road sound barrier and refer to the opinions of professionals to choose a suitable sound barrier in order to better isolate the noise.
