The Subjective Assessment of Soundscape in Campus — Taking YaoHu Campus of Jiangxi Normal University for Example

Abstract:

In order to the search for more effective noise control measures and a more rational urban planning from the angle of economy, environment, so that we can create a healthier living environment, this paper does some preliminary investigation in the aspect of soundscape. This paper introduces soundscape science research status and research results domesticity and abroad, and on this basis, makes a subjective evaluation of voice of the landscape in Jiangxi Normal University, by combinating Psychoacoustic Evaluation Method. This paper record various of sounds existing in the campus, analyses properties of each sound, and does a large-scale survey about the popularity of these sounds. The paper chooses ten most popular voices using mark-giving method, and analyses the ten 10 kinds of sound by SD methods. The following are the results: (1) the ten most popular voices in the campus: voice of birds, sounds of musical instruments, voice of singing、reading、and teachers’ lectures, and the sound of radio(music)、 broadcasting (in English and other programs)、computer sound (music, film sound) and wind，50% of which are natural sounds, 30% human voice, and 20% noise of machines. From above, we can see that the sounds from nature are more acceptable. (2) By using semantic differential method (SD Act), the paper does a subjective evaluation on the ten popular kinds of voices. Marks are different form different analysing angle, that is, different people like different voices on different degrees. (3) When people work and learn, it is good to create some comfortable sounds in the surroundings and control or eliminate noisy sounds. Creating a comfortable sound surrounding environment is a good way to improve people’s working and learning effeciency.
