Railway noise barriers are between 1m and 5m in height, and the effective coverage area has an average noise reduction of 10-15dB(A) (125Hz-40000Hz, 1/3 octave), **up to 20dB(A). Generally speaking, the higher the railway sound barrier, or the farther away from the sound barrier, the better the noise reduction effect. The construction of railway sound barriers is mainly to create a noise-free environment for residents on the side of the railway. Product features: modular design, flexible, quick, and convenient installation, and disassembly; large sound insulation, high sound absorption coefficient, high strength, strong weather resistance, beautiful appearance, convenient installation and maintenance, and various colors of railway sound barriers (sound insulation) can be sprayed according to user needs Wall) use: widely used in high-speed railway, intercity railway, urban light rail, and other sound barrier projects. Technical parameters of railway sound barrier (sound insulation wall): 1. Sound insulation: 46.3dB (A); 2. Sound absorption coefficient: 0.87; 3. Wind pressure resistance: 3-second gust wind pressure (P=±3.00KPa) test **Large deformation 29.5mm **Large residual variable 8.00mm Common specifications of railway sound barriers (soundproof walls): 1960mm×500mm×100mm (length×width×thickness). Noise barrier application environment, railway noise barriers are divided into traffic noise barriers, equipment noise attenuation noise barriers, and industrial plant boundary noise barriers. In general, indoor sound barriers use steel plates, wood panels, gypsum boards, and foam aluminum structures; outdoor sound barriers use brick or concrete structures. Nowadays, the 2.5-meter-wide PC board has been successfully developed, which greatly improves the light transmission effect and enhances the impact resistance, weak acid, and neutral oil resistance of the sound barrier. The service life is also longer, and the effective use period is as long as 20 years.
