Investigation and Optimization Research of Soundscape in Linyi University Campus, Shandong, China

As an important part of the landscape, campus soundscape has an important impact on campus life for teachers and students. Taking the campus of Linyi University as an example, this paper explored the current situation and constituent elements of the campus soundscape through the soundwalk approach and instrument measurement. The results show that the sound levels of the teaching area, teaching auxiliary facilities area and green area of Linyi University basically meet the national standards, while the dormitories, restaurants, sports fields and other areas exceed the standard due to a large number of students and relatively concentrated influence, and the main gate always exceeds the standard due to the influence of traffic flow and external traffic. There are abundant elements of soundscape on the campus of Linyi University, which can be divided into four categories: natural sound, artificial sound, traffic sound and mechanical sound. The frequency of talking, footstep, motorbike and bird song was the highest on weekdays and rest days. Due to a number of electric bicycles that exist, the sound of electric bicycles has a bad impact on the overall landscape image of the campus. Finally, some suggestions are put forward in terms of increasing public transportation on campus, isolating sound sources outside campus, reducing noise in the dormitory area and protecting and mining natural sound elements.
