Noise barriers for airports. Noise barriers are structures built to mitigate the impact of noise pollution on the surrounding environment. In the case of airports, noise barriers are particularly important as aircraft engines generate significant levels of noise that can cause disturbance and annoyance to nearby communities. These barriers are designed to absorb, reflect, or deflect sound waves, reducing the noise levels that reach the ground. They can be constructed using various materials such as concrete, steel or wood and may take the form of walls, berms, or other configurations. Effective noise barriers can improve the quality of life for nearby residents and help airports comply with noise regulations.
