Noise Control along the Beijing-Shanghai High-Speed Railway

The Beijing-Shanghai High-Speed Railway spans across seven provinces and municipalities: Beijing, Tianjin, Hebei, Shandong, Anhui, Jiangsu, and Shanghai, connecting the Bohai Economic Rim and the Yangtze River Delta Economic Zone. The population along the route accounts for a quarter of the national total. With a total length of about 1318 kilometers, the double-track railway comprises predominantly bridges, with a length totaling 1061 kilometers, accounting for 80% of the entire route. In 2010, noise control facilities were installed along the railway route, consisting of railway sound barriers made of aluminum alloy. These sound barriers can reduce noise levels by over 30 decibels, with a noise reduction coefficient exceeding 0.7, effectively mitigating the impact of noise along the railway line.
