Noise barriers are structures designed to reduce noise pollution, especially from busy roads, highways, or railways. They are typically made of materials like concrete, wood, or plastic and are placed between the noise source and residential areas. By blocking sound waves, these barriers help create a quieter environment for people living nearby. These barriers can also enhance the landscape by incorporating greenery or artistic designs. In addition to improving quality of life, noise barriers can protect wildlife habitats by minimizing disturbances from human activities. Overall, they play a crucial role in urban planning and community well-being, making areas more peaceful and enjoyable.
