The height of the highway sound barrier is between 1m and 15m, and the average noise reduction in the effective area covered is 10-15dB (A), with a maximum of 30dB (A). Generally speaking, the higher the sound barrier, or the closer it is to the sound source, the better the noise reduction effect. Currently, most sound barriers use a mixture of sound absorption and insulation products, which are characterized by targeted control of the generation and transmission characteristics of road noise. For example, the sound of cars rubbing against the road or vehicles rubbing against the track is located at the lower part of the road, and the sound has the characteristic of being diffracted through the upper part of the screen. Therefore, a structure with upper and lower sound absorption and middle sound insulation is adopted in the design, which can effectively reduce the diffraction of noise. A transparent reflective sound insulation plate is used in the middle of the sound barrier, which can effectively interrupt the transmission path of sound waves, and also provide a wide visual environment for drivers and residents.

Characteristics of highway sound barrier:

1. Combined design, flexible and convenient for installation and disassembly;

2. The straight and flat highway sound barrier has a flat overall shape, while the upper sound absorption plate is arc-shaped, which can more effectively diffract sound through the upper part of the screen in space, with a continuous frame structure as the main body in the middle;

3. Fox shaped highway sound barrier, which is beautiful and has good noise reduction effect;

4. The road sound barrier sound-absorbing board not only has good sound absorption and insulation effects, but also has excellent weather resistance and durability, ensuring its service life;

5. Multiple colors and shapes can be selected for combination, with ideal landscape effects. According to user requirements, various forms can be designed to harmonize with the environment, coordinate with the surrounding environment, and form a beautiful landscape.
