Discussion On The Role Of Environmental Factors In Soundscape Evaluation

Under the high-speed economic development, urbanizationprocess brought too much passive voice to people’s living environment, which madethe ecological and social value soundscape research more prominent. With thedevelopment of different discipline such as architecture, ecology, environment,psychology and Landscape, it is widely believed that the evaluation and retrofit ofenvironment should no longer be limited to the visual. Soundscape should be planedand protected reasonable as a kind of natural resources. However up to now, theinfluence factors of sound scene does not have a final conclusion. No relevantregulations and standards on its evaluation methods has been unveiled in theinternational world. The evaluation mechanism of soundscape is not perfect.This article summarized the two kinds of sounscape evaluation commonly used athome and abroad, analyzed the close relationship between the subjective evaluationresults and variety of environmental factors in open environment bathed on theresearch of different evaluation and design methods on soundscape. The soundscapemodel which based on environmental factor statistics has been set, with Specificenvironmental data as the independent variables and soundscape subjective evaluationresults as the dependent variable. It tried to discuss the environmental impact factorsin soundscape evaluation from the perspective of environment.The main content of research includes the following five aspects:1. The development history and domestic and foreign research situation ofsoundscape has been mastered. We separate the soundscape research in differentaspects including research contents and research methods. After that the researchcontents, research object and technical route has been established.2. Made subjective evaluation on Henan agricultural university by usingintegration listening and description listening methods. Measured data of equivalentcontinuous A sound level, green cover percentage, building coverage, speciesdiversity, species richness by collecting objective information of specific factors in the environment.3. After summarizing soundscape evaluation content and soundscape indexesdifference drawing, we visually analyzed relationships between campus soundscapeand the indicators. Applied descriptive statistics, correlation analysis, partialcorrelation analysis, stepwise multi-regression analysis of environmental data and theevaluation results we collected the relationships among various environmental factorsand soundscape evaluations. In the end he subjective evaluation model has been builtwith Specific environmental data as the independent variables and soundscapesubjective evaluation results as the dependent variable.4. Under the guidance of statistical analysis results and soundscape evaluationmodel, multi-layer steamed bread mode has been used to discuss the design andretrofit methods of soundscape in Henan agricultural university.5. On the basis of summarizing each step of analysis results, we discussed thedeficiency of research, pointed out the remained further research direction...
