Abstract: ［Objective］ With the increasing rail transit network density and the expansion of environmental noise-sensitive areas, the issue of noise radiation caused by rail transit is becoming increasingly severe. It is therefore necessary to conduct an in-depth analysis of environmental noise impact assessment standards for rail transit in China. ［Method］ The evaluation volumes, frequency ranges, and weighting methods involved in the environmental noise assessment standards for rail transit are outlined. Additionally, relevant standards for rail transit environmental noise in recent years are summarized to clarify the specific evaluation methods, indicators, and limit settings. ［Result & Conclusion］ Through a systematic review of the fundamental parameters for noise description and measurement, the aspects of the current standards that require revision are identified.
