Objective Evaluations Based on Urban Soundscape in Waterfront Recreation Spaces

Space and form play an important role in the current geometry of recreational space and cognition of sound field. Therefore, there is different objective physical quantity information of sound energy. These concerned sounds are related to urban development and historical and cultural characteristics and will be highly recognizable sounds. It can be seen from the above that in urban recreational streets, through the objective physical characteristics of the street sound field sorted out, the positive evaluation can be predictably given, and the correspondence between the subjective feelings of the people will be explored. If the physical quantity of sound energy discusses the homogeneity of normalization of the soundscape and comprehensive physical quantity information, it is afraid to ignore the characteristics of spatial qualitative and internal variability. The currently research results propose the urban soundscape acoustic environment factors of waterfront recreation spaces, confirm and draw distinctive sound energy distribution maps and sound field perception. Understand the public's sensitivity and preference for sound, and explore the correlation and consistency of measurement and computer simulation correspondence.
