A sound barrier is a structure made of materials designed to reduce or block sound transmission between two areas. The barriers are typically made of dense materials such as concrete, masonry, or metal.
The basic principle behind a sound barrier is to reflect and absorb sound waves. When a sound wave encounters a solid surface, the wave is either reflected or absorbed. The sound barrier is designed to reflect as much sound as possible back towards its source, and to absorb as much sound energy as it can.
The height and placement of a sound barrier are also critical factors in its effectiveness. The barrier should be tall enough to effectively block the sound from reaching the other side, and should be placed as close to the sound source as possible.
Sound barriers are typically used along highways, railways, and near airports to reduce noise pollution for local residents. They can also be used in industrial settings to reduce noise levels for workers.
