What should we pay attention to when installing highway sound barriers?

The position of the highway sound barrier should be set at the level of the sound barrier, as close as possible to the sound source. The effect is not obvious 100 meters away.

The height of the highway barrier is also limited, generally within 3-4 meters, and the high-rise buildings have a good sound insulation and noise reduction effect, so the residents adjacent to the high-rise buildings along the highway will still be affected by a certain degree of noise.

The traffic volume of highway noise is huge, and the noise decibel exceeds the urban living environment standard, which has passed the environmental protection evaluation.

The highway sound insulation wall, especially the bridge section, is limited by the foundation structure and road traffic safety. When adding the sound insulation wall, the bearing capacity of the road should be considered.

The sound barrier is a wall-like structure, especially the long section of the road will narrow the field of vision of the road, affect the travel of light, and is more dangerous when installed.

There is also an installation that affects people's view of nature, so the installation of highway sound insulation walls cannot affect light.

The metal sound barrier of the highway is composed of an isolation box, connectors and fasteners. Most of the noise on the highway enters through the blinds and is absorbed by the sound absorption and filling materials.
