noise barriers highway ，acoustic barrier ，construction noise barrierWhen sound waves hit the surface of these materials, they will enter the pores of the sound-absorbing material, causing the air in the pores and the fine fibers of the material to vibrate. Due to friction and viscous resistance, sound energy is converted into heat energy, which is absorbed and dissipated. The better the sound absorption performance of the sound-absorbing material, the greater the surface accumulation, and the better the noise reduction effect. The sound insulation board material can be galvanized or aluminum. Use numerical control equipment to press the surface of the board into shutters or round holes, and then use professional hemming technology on the hem. In order to show the cutting effect of the sound barrier, choose the installation length of the sound barrier reasonably. The height of the protection object must be less than the height of the curved sound barrier, so that the curved sound barrier has a better effect.

Since the noise reflected by the reflective surface will not contact the sound barrier, the noise reduction effect of the sound barrier will be greatly reduced. The sound barrier is close to the noise source, convenient for construction, small area, and good economy. This not only caused heartbreaking losses to the country, but also destroyed the urban landscape. The combination of solar heat collection and sound barrier can make full use of the area of the sound barrier to achieve the purpose of comprehensive utilization.

During transportation construction, the steel bars in the concrete may break and be stolen, not to mention the soundproof metal shielding materials on the road. Therefore, the anti-theft design component of this sound insulation material should be used frequently due to its simple structure, short construction period and high installation standards. Acoustic design should consider loads, such as dead weight, wind load, train pulsation, etc. The design load of the noise barrier must be integrated according to the load that can act simultaneously during use.

Close to our view, a relatively primitive road noise barrier appeared. It is common that every major road has a row of noise barriers, and this style is still increasing. Compared with the original cement sound insulation barriers, the current metal sound insulation barriers and transparent sound insulation barriers have increased in equipment and applications, which are not only beautiful and advanced, but also the noise reduction effect of cement compared with sound insulation barriers. Great improvement.
