Decorative Railways perforated metal acoustic panels sound barriers fence

Railway sound barrier is divided into pure sound insulation reflective railway sound barrier and composite railway sound barrier combining sound absorption and sound insulation. The latter is a more effective sound insulation method. It refers to the wall structure set beside the railway and highway to reduce the impact of traffic noise on nearby residents.
Railway sound barrier is also called sound insulation wall. Insert a facility between the sound source and the receiver to make the sound wave propagation have a significant additional attenuation, thus reducing the noise impact in a certain area where the receiver is located. Such a facility is called the railway sound barrier. It is divided into traffic noise barrier, equipment noise attenuation noise barrier, industrial boundary noise barrier, highway and expressway where the most types of railway noise barriers are used.
Most of the railway noise barriers are sound absorption and sound insulation hybrid products, which are characterized by targeted control of the generation and transmission characteristics of road noise. Transparent reflective sound insulation board is used in the middle of the railway sound barrier, which can effectively interrupt the transmission path of sound waves; At the same time, it also provides a wide visual environment for drivers and residents.
