The Daxi High-Speed Railway, stretching from Yuanpingxi Station to Xi’an North Station, spans a total length of 859 kilometers. In 2013, noise control facilities were installed along the railway route, consisting of railway sound barriers made of aluminum alloy. These sound barriers are capable of reducing noise levels by over 30 decibels, with a noise reduction coefficient exceeding 0.7, ensuring the reduction of noise impact along the railway line.
