Abstract: By taking the front squares of Taiyuan Station and Taiyuan South Station as examples, a combination of objective measurement and subjective questionnaires is used to investigate and study the acoustic environment of station squares. The survey results show that the acoustic environmental quality of the front squares of the two stations basically reaches the standard, but the noise levels in some areas exceed the standard. Profited from the reasonable overall planning and the establishment of green belts, the acoustic environmental satisfaction in the front square of Taiyuan South Railway Station is relatively high. Noise from social life is the main sound source in the front square of the station, among which the broadcasting sound is dominated, and the train sound is the unique source there. Based on semantic difference method and factor analysis method, the research shows that the acoustic environment in the front squares of the station is generally comfortable and interesting, and the intensity and abundance of the sound source are relatively high. Finally, some suggestions are put forward to solve existing acoustic environment problems and improve acoustic environmental quality in the front squares of station, which provides a reference for the construction of such spatial soundscapes.
