An acoustic barrier is a structure designed to reduce noise pollution by blocking or absorbing sound waves. Commonly used in urban areas, these barriers can be made from various materials, such as wood, concrete, or specialized sound-absorbing panels. They are often installed along highways, railways, or near industrial sites to protect nearby residents from excessive noise. The effectiveness of an acoustic barrier depends on its height, length, and the materials used. Properly designed barriers can significantly lower noise levels, improving the quality of life for those living in close proximity to loud environments. They are an essential tool in urban planning and environmental management.
