Noise Control of Shinkansen and Its Reference Significance to China

Abstract

Japanese society has always been concerned about noise issues in the environmental protection of high-speed railways, and various efforts have been made administratively and technically to address high-speed railway noise issues. Administrative efforts include regulatory measures such as setting environmental standards for high-speed railway noise and noise measurement and assessment; technical efforts include testing and control using appropriate means for various railway noise sources. The environmental noise problem of the Shinkansen has become one of the key factors limiting the ability of the Shinkansen to increase its operating speed. China's high-speed railway construction has been developing rapidly since 2008, and increasing attention is being paid to environmental protection. With the increase in China's high-speed railway construction lines and the gradual increase in high-speed railway speed, China's high-speed railway’s new higher-speed technology shall be put into operation in the future. The issue of high-speed railway noise control is also becoming increasingly important to China. China's high-speed railways have applied both active and passive noise reduction technologies, but in view of the research on high-speed railway noise control the concept and design of environmental protection, especially noise control, of the Japanese Shinkansen railway was carried out relatively early, and the research on advanced technology of some Shinkansen noise control measures has certain significance for China's high-speed railway operations.
