Garden Soundscape Evaluation And Optimal Design Research

With the development of the economy,the user's demand for the environment is getting higher and higher.In the past,environment design usually emphasizes the visual landscape and ignores the sense of the people's hearing.However,as a whole,acoustical elements are also an important part of the environment,which has gradually attracted the attention of scholars.As a type of green space,as well as a humanistic tourist attraction with great research value,garden has become a popular research object of soundscape in recent years.The existing research on soundscape is mainly concentrated in the field of garden in the south of the Yangtze River.As one of the important branches of domestic gardens,the soundscape of gardens in Fujian and Taiwan should also be paid attention to by users and decision-makers.As the representative work of Fujian and Taiwan gardens,the Shu Zhuang Garden has its own unique soundscape.With rich cultural connotation and many literature historical materials can be studied,it has become the soundscape study case in this paper.The main contents of this paper are as follows:This paper first collects the information about the related research on soundscape at home and abroad,summarizes the research status and the existing achievements,and makes clear the direction and purpose of the research.Then with the combination of the related disciplines such as landscape aesthetics,landscape ecology and environmental psychology,we find that key point of the study of garden soundscape is the evaluation and optimization of the acoustical elements.The composition of the acoustic elements and the proportion of the acoustics are obtained through the research on the literature of the garden and the survey of the sound scenery.The acoustic environment data of the site are collected with the acoustic indexes,and the present situation of the soundscape in the park is analyzed.Then we choose the fuzzy evaluation system to combine the subjective and objective views.With mathematical statistics,the sound elements and garden elements in the garden are analyzed.The subjective evaluation of the public visitors' auditory perception,physical environment and feasibility indexes is studied to quantify the subjective feelings of the people and combine them with the objective test.The corresponding measures for soundscape improvement are put forward,and some scenic spots are optimized according to the gardens themselves.Through the study of the Shu Zhuang Garden,the present situation and evaluation results of the soundscape of the park are obtained,which provides a new possibility for the quantitative study of the subjective evaluation of the soundscape.It also provides a reference for the landscape designers,through the improvement and optimization of the soundscape.At last in this paper,the limitations of acoustic landscape research in the present stage are summarized,and the future direction of acoustic landscape research in the field of acoustics is anticipated.We also pointed out the possibilities of using future soundscape in different architectural scenes,which will provide an innovative idea for the follow-up study of soundscape.
