Railway sound barriers， railway sound barrier prices， railway sound barrier manufacturers The transparent sound insulation board uses a transparent polycarbonate board (also called a PC board), which consists of one and two. The height of the four previous sound barriers can be freely combined according to design requirements. The other polycarbonate board was not perforated, and the distance between the two layers was 100 mm. The back and side panels are made of non-porous galvanized steel. The standard plate is inserted between the I-beams and fixed with fasteners for easy installation, maintenance and replacement.

The sound barrier of the air conditioner uses a hybrid sound barrier, with a sound absorption unit at the top and a sound insulation unit at the bottom. The module can be configured arbitrarily. The sound barrier of the air conditioner is mainly composed of a base, a column and a vertical screen. Although noise pollution provides great comfort for people's influence and travel, it has also become a prominent social problem, and noise barriers have become an effective way to solve this problem.

In order to prevent the sound source from reaching the receiver, the sound propagation will produce significant additional attenuation, thereby reducing the impact of noise on the receiver in a given area [2]. Let a good landscape maintain a dynamic balance that is conducive to physical and mental development [3]. In order to effectively control traffic noise and strengthen the environmental protection of roads, sound barriers are widely used to control road noise due to their practicality and effectiveness. On the premise of meeting the requirements of noise reduction, determine the noise design goal and sound insulation design height to save investment costs.

A large number of studies have shown that it is very simple to insert standard plates between I-beams and fix them with fasteners. It is equivalent to a single-layer microporous sound-absorbing structure. There are two layers of microporous plates for transparent sound insulation. The composite sound barrier has the advantages of transparent and opaque sound barriers. The isolation material is required to be relatively loose.
