Noise barrier are structures that are designed to reduce noise pollution in high traffic areas, such as highways, airports, and industrial zones. In Singapore, noise barriers are commonly used in urban areas to mitigate the impact of traffic noise on nearby residents. Noise barriers are typically made from materials such as concrete, steel, and acoustic panels, which can absorb and deflect sound waves. The effectiveness of noise barriers depends on their height, width, and placement. When properly designed and installed, noise barriers can significantly reduce noise levels and improve the quality of life for nearby residents.
