Analysis And Optimization The Soundscape Of Public Space In Urban Residential Area Of Wuhan

As an important part of the city,residential areas generally occupy the largest proportion of the five major types of land use.In urban life,about 2 / 3 of the time spent in residential areas.With the improvement of people's living standard,the environmental quality of public space in residential areas has attracted more and more attention.However,for a long time,the design of public space has always paid attention to the visual angle,and neglected the design of hearing.At the same time,with the development of urban construction,the increase of traffic flow and the increase of noise sources,the environmental noise in residential areas is becoming more and more serious.Sound environment has become a short board of human settlements in a sense.In order to create a healthy and beautiful residential space,public space,sound and landscape,and to deal with environmental noise.On the basis of soundscape theory,through the investigation,evaluation,analysis and experiment of soundscape in residential area of Wuhan,the existing problems of soundscape are summarized and some optimization suggestions are put forward.The full text conclusion can be divided into 5 parts according to the chapter:(1)Objective data--Research on space law level distribution and law of time,found that the main problems existing in the research field for the "traffic" is too large,the traffic flow and the multiple regression equation is: y=68.807+0.0001 x1+0.002x2+0.015x3,log linear regression equation: y =54.995+2.5898In(x).(2)Subjective evaluation--Research on subjective evaluation of soundscape three elements(voice,user and environment)the relationship between mutual influence,found that 20% of the green rate is a watershed research site,at this level,respondents subjective acoustic comfort evaluation is poor,and can improve the level of good evaluation.After the rate of green space exceeds 40%,the span of improvement of subjective sound comfort is becoming smaller.(3)Cadna/A simulation--Research on the law of sound attenuation in different environments,and try to use software to assist the design of dynamic and static zoning in public space,and verify the partial results of objective data and subjective evaluation.(4)VR experimental--Research on how to improve the evaluation of the voice of the people,compared the different as the rate of green under a variety of soundscape elements that effect of soundscape good improvement scheme is to increase the soundscape elements at the same time increase as the rate of green.(5)Optimization suggestion--Combined with the previous research results,the author gives the concrete suggestions of optimizing the soundscape from three angles of negative design,zero design and positive design.
