With the continuous development of urban traffic, as an important part of urban traffic, the traffic noise problem brought by viaducts has become increasingly prominent. In order to reduce the impact of viaduct traffic noise on the surrounding environment and residents' lives, sound barriers are widely used as an effective noise reduction facility. Today, we will take you to learn more about the noise reduction effect and types of viaduct sound barriers. 1. Noise reduction effect of viaduct sound barriers The main function of viaduct sound barriers is to absorb and reflect traffic noise, thereby reducing the propagation and diffusion of noise. Its noise reduction effect mainly depends on factors such as the material, structure and height of the sound barrier. Generally speaking, the average sound insulation of the sound barrier can reach about 36dB, which means that under the action of the sound barrier, traffic noise can be reduced to about 1/4 of the original, significantly improving the quality of the surrounding environment. At the same time, the average sound absorption coefficient of the sound barrier is also high, usually maintained at about 0.83. This means that the sound barrier can not only effectively block the spread of noise, but also absorb part of the noise, further improving the noise reduction effect. 2. Types of viaduct sound barriers According to the different shapes and structures, viaduct sound barriers can be divided into many types, each of which has its own unique characteristics and applicable scenarios. 1. Vertical sound barrier: This sound barrier has a simple structure and is easy to install. It is suitable for elevated bridge sections with limited space. Its upright design can effectively block the propagation path of noise and achieve a good noise reduction effect. 2. Top arc sound barrier: This sound barrier adopts an arc design at the top, which can not only increase the height of the sound barrier and improve the noise reduction effect, but also reduce wind resistance to a certain extent and improve safety. 3. Angle sound barrier: The angle design can make the sound barrier better adapt to the direction and surrounding environment of the elevated bridge, improve the noise reduction effect, and maintain a good landscape effect. 4. Overall arc sound barrier: The overall arc sound barrier adopts a smooth arc design, which is not only beautiful, but also can effectively reduce wind resistance and noise diffraction, and improve the noise reduction effect. In addition, according to different materials, sound barriers can also be divided into metal sound barriers, concrete sound barriers, PC sound barriers and fiberglass sound barriers. These different types of sound barriers have their own advantages and disadvantages in terms of noise reduction effect, durability and cost, and need to be selected according to specific needs and conditions. As an effective facility to reduce traffic noise, the noise reduction effect and type selection of viaduct sound barriers are of great significance to improving the surrounding environment and improving the quality of life of residents. Jinbiao warmly reminds you: Only by reasonably selecting the type and material of the sound barrier, and designing and installing it in accordance with the actual situation, can the noise reduction function of the sound barrier be maximized to create a more peaceful and comfortable living environment for urban residents.
