Sound insulation barrier manufacturers believe that with the rapid development of cities in modern society, the problem of noise pollution has also followed. As the four major pollution sources, noise pollution is very harmful to people's lives, so that it affects our living environment, makes us helpless, and seriously affects our lives. How to effectively and quickly control noise pollution and control the noise that originally affects our normal life within an acceptable and unaffected range has become an urgent and important issue. Noise is also systematically divided into four categories (mechanical noise, aerodynamic noise, traffic noise, and social activity noise).

In the past, the construction period for noise reduction was relatively long, and the cost was relatively high, and the effect of noise control was also suitable for that time. Here we will talk about the noise reduction of the sound insulation barrier. The sound insulation barrier has a small footprint and a fast construction speed. It is relatively affordable in terms of cost and maintenance costs in the field of noise reduction. It can effectively block noise without damaging the overall architectural landscape. This is the currently recognized noise control method in China.

Sound barriers are mainly used to block the direct transmission of noise sources. Setting up a sound insulation barrier between the noise source and the receiving machine can effectively control the transmission of medium and high frequency noise from the noise source, and isolate a local quiet environment in the noise environment.

Using sound insulation barriers to control noise pollution and keep one place quiet is one of the important contents of improving people's livelihood. It is more and more important in people's life. For example, construction noise refers to the sound generated during construction that disturbs the surrounding living environment. Construction noise comes from many aspects, and it is also multi-category and complex. According to the author's investigation, it mainly comes from the four construction stages of earthwork movement, piling, structure pouring, and decoration. The main noise-pollution equipment includes: bulldozers, excavators, loaders, various pile drivers, concrete mixers, chainsaws, cranes, elevators and other power machinery with different performances.

With the progress of the sound insulation barrier project, the construction machinery and methods used in the construction are different, and the noise sources of the sound insulation barrier building will also be different. For example, in foundation engineering there are earth blasting, trench excavation, leveling and site clearing etc. In the main sound barrier project, there are operations such as erecting steel skeleton or reinforced concrete skeleton, hoisting components, mixing and pouring concrete. At the construction site of the sound insulation barrier, there are frequent activities such as transportation, loading and unloading of materials and components; in addition, there are various beatings, impacts, collapse of old buildings, people's shouts and so on. Since most construction machinery works in the open air, there is no shelter around, some machinery needs to move frequently, and the hoisting and installation work requires high-altitude operations, so some noise during construction is characterized by suddenness, impact, and discontinuity, which is harmful to surrounding residents. has a great impact.
