High-speed sound barrier, guardian of noise reduction and environmental protection

High-speed sound barriers, as important facilities for modern traffic noise control, have been widely used on both sides of expressways, railways, and urban elevated roads. They not only effectively reduce the impact of traffic noise on surrounding residents and the environment but also have multiple hidden functions, becoming an indispensable part of urban transportation construction. The main function of high-speed sound barriers is sound insulation and noise reduction. Its working principle is to insert a barrier between the sound source and the receiver, so that the sound waves are attenuated during propagation, thereby reducing the noise level in a specific area. Sound barriers usually use sound-absorbing materials and structural designs to effectively absorb and reduce the propagation of vehicle noise, protecting the peace and quiet of surrounding residents and the environment. Studies have shown that the average sound insulation of sound barriers can reach 36dB, and its average sound absorption coefficient also remains at a high level, about 0.83, showing noise reduction performance. In addition to sound insulation and noise reduction, high-speed sound barriers also have multiple hidden functions.

Let's discuss whether bridge noise barriers are effective for high-rise residential buildings.

Are bridge sound barriers useful for high-rise residential buildings? Many residential users are concerned about this issue. After the installation of bridge sound barriers, they also help high-rise residential buildings. After the sound is blocked by the sound barrier, it will float from the top, which will greatly reduce the noise, but the specific noise reduction level depends on the height of the sound barrier and the distance of residents from the sound barrier! It is recommended to use sound hole or louver type sound barriers. Measurements of the noise reduction effect of bridge sound barriers on high-rise residential buildings were conducted over a wide range in the height direction. By monitoring the sound pressure levels of different floors of high-rise buildings before and after the construction of sound barriers, it was found that the sound barriers had a significant noise reduction effect on low-rise buildings, and the best noise reduction effect was on the 6th floor. Outside the sound shadow area, the sound barriers still have a noise reduction effect on noise-sensitive buildings, and the noise reduction effect decreases with the increase of building height. The density of vehicle distribution on different lanes has different effects on the noise reduction effect of sound barriers. Bridge sound barriers have a significant noise reduction effect. Nowadays, the method used in traffic is to install sound barriers to reduce noise, the decibel reduction is large, it can meet the noise reduction standard, and it provides a quiet environment for people's life, work and study. Moreover, sound barriers not only consider noise reduction, but also consider landscape effects. In order not to damage the surrounding environment, there are many types of sound barriers to choose from, and now transparent sound barriers are also available.
