Analysis Of Soundscape And Research Of Soundscape-mapping Based On GIS

The concept of soundscape has spread from the original "music in the environment "to the environmental acoustics,it has important influence on the traditional landscape design.The fusion of sound and scene has become a new trend of the development of the urban landscape design and construction.The research and application of soundscape was one of the hot spots on study of acoustic environment,landscape construction.This paper has studied the production and application of soundscape based on GIS.The detailed investigation and analysis has carried on the existing soundscape research,the framework of soundscape mapping was established based on GIS;Based on soundscape mapping studied on the mutual influence relations of sound and scene in the city,to guide the design and construction of urban landscape;the concept of soundscape walk was put forward in soundscape mapping,the research and analysis of soundscape was innovational.The main work of this paper included the following three parts:Through using urban GIS database resources,on the GIS platform,the relevant professional computing software,and investigation and analysis results of measurements and subjective was integrated to make urban soundscape mapping.In this paper the willows park as an example,which was one of the ten views of Hangzhou west-lake,expounded the process of the figure of soundscape mapping,which would be the guidance for other areas to carry out.On the platform of soundscape mapping,the research of the sound,landscape design and construction was carried out.Through the analysis of spatial dimension,on the graph soundscape construction area and noise control area were divided.In the noise control area,the landscape design was mainly around how to control traffic noise.In the soundscape construction area,according to the different characteristics of sound and scene divided into different types of soundscape construction area,create a distinctive soundscape respectively.Through the analysis of time dimension,reveals the rules of soundscape in the park,grasp the characteristics of soundscape.Through the analysis of cultural dimensions,to discover the identity of the acoustic elements in the park,the characteristic soundscape was build,which making sound,scene and person unity,and becoming bright spot in the park.In the graph,through the analysis of sound comfort,the scope of the traffic noise buffer was precisely divided out,that making the design of soundscape targeted.Through analysis of the identified sound elements,put forward the concept of "soundscape walk",which in the park mainly focused on building soundscape area of identify sound,on the map the best path to enjoy the soundscape was displayed,that would bring the visitors different experience and feelings than before.Finally through the WebGIS platform,soundscape mapping would be opened on the Internet,to guide the public to feel the city's soundscape,promote the whole society's attention and improve the acoustic environment of the city,retention and looking for cultural and historical sense of sound elements,promote the quality of the landscape design and construction.
