Study On Soundscape Evaluation And Optimization Strategy Of Comprehensive Park In Tianjin City

With the development of the city,people’s living standard has been greatly improved,the quality of the living environment is also put forward higher requirements,the environmental problems in the process of economic development gradually makes people begin to pay attention to creating and maintaining the natural environment.In the limited space of the city,how to maximize the quality of the environment and the effect of the landscape,designers are faced with the problem.In order to make the city park environment more meet the needs of the development of the modern society,we must find the method is more comprehensive,more levels based on traditional landscape design methods,To create a soundscape is an effective way to improve and enrich the park environment.The goal of this paper is to analyze the existing problems in the current environment,and then put forward the optimization strategy after the subjective evaluation and objective analysis of the overall environment of the park.First of all,the paper describes the current situation of domestic and foreign sound landscape research,summary of feasible experimental methods,established by soundwalk experiments on subjective evaluation in three comprehensive parks in Tianjin,and analyzing the sound characteristics and status of environment in the landscape pattern,landscape plants and psychoacoustic parameters.Using statistical methods,the subjective evaluation and objective data were analyzed to find out the main factors that affect the park environment,and the optimization strategy of different functional areas was divided into.The results showed that there was a strong correlation between the visual comfort of the comprehensive park landscape and the sound comfort level and the overall environmental comfort in Tianjin city.The sound environmental diversity index of the park is dominated by the active voice,and the effective means of improving the sound environment of the park have to enhancing the natural sound people like,and reducing the activity of the sound.Activity square need to focus on to control activities;the natural effect of landscape nodes need to focus on hearing environment,natural attraction,activities;landscape nodes surrounding roads should pay attention to the distribution of landscape pattern;distinctive regional activities need to be visual environment layout more cultural characteristics,while focusing on the effect of activity itself.In addition,the use of plant landscape can not only improve the visual environment,but also the use of the attraction of the plant itself to improve natural sound,to reduce the interference between different functional areas of sound.
