This example provides a closed-structure elevated sound insulation system for elevated roads, which is used for sound insulation of elevated road noise.

The elevated sound insulation system uses ETFE (ethylene-tetrafluoroethylene copolymer) air pillows as sound insulation elements. The ETFE film material has good sound insulation and sound absorption capabilities, and the ETFE air pillow composed of it has multiple layers of ETFE films, and the interior is filled with air to form an air pillow, which will have good sound insulation and sound absorption capabilities.

Optionally, the ETFE air pillow can be in the form of a double-layer or multi-layer air pillow. The double-layer ETFE air pillow has two layers of ETFE films, and the multi-layer ETFE air pillow has 3 to 4 layers of ETFE films. After the multi-layer membrane is inflated, it can improve the ability of sound reflection, and finally achieve high-efficiency sound insulation on the road.

Furthermore, ETFE air pillows have high light transmittance, and the light transmittance of a single-layer film can reach 95%; light reflectivity is weak, which can reduce light pollution; good anti-fouling properties, the main dirt can be removed by rainwater, which can effectively improve the quality of elevated roads.
