In modern society, major traffic arteries and industrial plants are the main sources of noise pollution, seriously affecting the lives and work of the surrounding residents. Noise barriers, as an efficient and common noise reduction facility, are widely used in highways, railways and factory areas, etc. They act like a "sound insulation wall", silently safeguarding the tranquility of the area.
The structure of the noise barrier is not complicated and mainly consists of three parts: a sturdy metal column serves as the framework, deeply embedded in the ground to provide core support; The main facade of the barrier is composed of metal screen bodies (such as aluminum alloy plates and galvanized steel plates), which are responsible for blocking and reflecting most of the sound waves. The sound-absorbing materials filled in the screen body (such as centrifugal glass wool) can effectively absorb and consume the energy of sound waves, reducing their penetrating power.
Its working principle is very easy to understand, mainly based on the principle of "blocking the sound wave propagation path". When noise propagates in the air and encounters a barrier, part of the sound waves are reflected back by the dense surface of the screen, while the other part enters the interior of the barrier and is converted into heat energy and consumed by the porous sound-absorbing material through friction and viscosity. By combining this method of "blocking" and "absorbing", noise barriers can effectively reduce noise decibels and create a significant "sound and shadow zone" during transmission, bringing tranquility to the other side.
