A noise barrier wall, also known as a sound barrier or acoustic barrier, is a structure designed to reduce the transmission of noise between two areas. These walls are typically installed along highways, roads, railways, or industrial areas to mitigate the impact of noise pollution on nearby residential or sensitive areas.
Noise barrier walls can be constructed from various materials, such as concrete, wood, metal, or specially designed sound-absorbing materials. They are strategically placed to block or absorb sound waves, reducing the level of noise reaching the protected area. The effectiveness of a noise barrier wall depends on factors like height, design, and the materials used in its construction. These barriers play a crucial role in enhancing the quality of life for communities impacted by high levels of ambient noise.
