Ljudvägg

Ljudvägg is a Swedish term that translates to "sound wall" or "noise barrier." It refers to a physical structure constructed to reduce sound propagation, particularly noise pollution. Ljudväggar are commonly implemented along highways, railway lines, industrial areas, and in urban environments to mitigate the impact of noise from traffic, machinery, and other sources on nearby residential areas and sensitive locations like schools and hospitals.

The effectiveness of a ljudvägg depends on several factors, including its height, length, density, and the presence of any gaps or openings. Materials used can vary and include concrete, brick, wood, metal, or specialized sound-absorbing panels. The goal is to block or absorb sound waves, preventing them from reaching the areas where noise reduction is desired. Design considerations often aim to integrate these barriers aesthetically into the surrounding landscape, sometimes incorporating vegetation to enhance their visual appeal and environmental benefit. The implementation of ljudväggar is a common practice in urban planning and environmental management to improve the quality of life for residents exposed to noise pollution.
