A road sound barrier is a facility that inserts a facility between the sound source and the receiver to provide a significant additional attenuation of the sound wave propagation, thereby attenuating the effects of noise in a certain area of ​​the receiver. Such a facility is called a sound barrier. Another way to convey sound is to communicate across media. That is, from one medium, through the critical contact surface of the two mediums into another medium, at this moment, the transmission of acoustic energy is essentially the transmission of oscillation fluctuations. When communicating across media, the greater the difference in density between the two media, the greater the loss of acoustic energy.
The installation of the sound barrier is of course to reduce the noise as much as possible, so how to install the sound barrier is a bit of a focus, which is also a feature of the noise barrier noise reduction, the material used for the sound barrier should also follow the performance indicators of the sound absorption board determine.
In general, the higher the sound barrier, or the farther away from the sound barrier, the better the noise reduction effect. According to the sound barrier application environment, the sound barrier is divided into traffic noise barriers, equipment noise attenuation noise barriers, and industrial plant boundary noise barriers. The outdoor sound barrier generally adopts brick or concrete structure, and the indoor sound barrier refers to the structure of steel plate, wood board, plastic plate, gypsum board and foam aluminum. The column is the main force-receiving member of the sound barrier, which is fixed in the groove at the top of the crash barrier by bolts or joints; the sound-absorbing sound board is the main sound-absorbing and sound-absorbing member, which is fixed to the H-type by the high-strength spring clip. A sound barrier is formed in the column groove. The design of the sound barrier has fully considered the speed of the expressway, the wind load of the city car, the natural wind load, the impact safety of the traffic vehicle and the all-weather open-air anti-corrosion problem.
Anping Heng'ai Road Sound Barrier adopts materials made of low-carbon and high-quality materials, which are made of high-quality imported materials. A large number of optimization measures have been carried out on the surface of the road sound barrier made of aluminum, so that the road sound barrier made of aluminum plate has the pliable characteristics that ordinary materials cannot have. The road sound barrier made of aluminum plate has super strong toughness in the normal use process, and its production process is very flat and simple, not only the texture is very uniform, but also made special consolidation during the production. Prevent unexpected damage.
