Noise Barrier
Basic conception
A sound barrier, also known as a sound wall or sound isolation wall, is a specially designed acoustic barrier usually placed between a noise source and a sound receiving point. It is mainly used for sound insulation and noise reduction, especially in highways, highways, elevated composite roads and other noise sources. Sound barriers can significantly reduce the impact of noise on the surrounding environment, especially in residential areas.
Structure and classification
-
Structure: The sound barrier is mainly composed of two parts: steel structure column and sound absorption screen plate. The column is the main stress component of the sound barrier, which is fixed on the embedded steel plate of the road anti-collision wall or the track side by bolts or welding. The sound insulation board is the main sound insulation and sound absorption component, which is fixed in the H-type column slot through the high-strength spring clip.Classification: By material: metal sound barriers (such as metal louvers, metal screen holes), concrete sound barriers (including lightweight and high-strength concrete), PC sound barriers, FRP sound barriers, etc. By use: railway sound barrier, highway sound barrier, urban landscape sound barrier, residential noise reduction barrier, etc.
Action and effect
- Reduce noise transmission: By reflecting, absorbing and blocking noise waves, sound barriers effectively reduce the impact of noise on the surrounding environment.
-
Improve the quality of life of residents: reduce traffic noise and other environmental noise, help to improve the comfort and quiet living environment.
Health protection: Reduce the negative effects of long-term exposure to high noise on human health, such as reduced sleep quality and hearing loss.
Protect the natural environment: reduce noise interference to the surrounding natural ecological environment.
Beautify the urban environment: The design of sound barriers can be combined with urban landscape planning to enhance the image of the city.
