The Analysis Of The Sound Environment Of Zhengzhou Jincheng Time Square And The Control Technology

Along with our country’s accelerating pace of urbanization construction,the new urban development and the old city’s transformation,our city population is growing and growing,and the residential area is also increasing.At the same time,even people’s living standard is becoming higher and their living style is much more various than before,the residential area noise pollution is increasily serious,which has a large effect on our quality of life and physical and mental health.People in the long-term noise polluted environment can be with the memory loss,decreased visual acuity,deafness,insomnia and fatigue and other symptoms,someone serious will appear depression,mental disease,heart disease,hypertension and even endocrine disorders,and for people that physical quality is weaker or older residents,injury caused by noise can not be repaired.Therefore residential noise control is imperative.However,China’s relevant standards and regulations for noise lags are far more behind other developed countries.We evaluate the decibels of sound environment of residential district only with this parameter,which has a great limitation.In addition,our country lacks detailed noise standard for internal acoustic environment in residential area,Therefore,our evaluation of acoustic environment inresidential district is too rough to fully reflect the quality of acoustic environment in residential district.In addition,we found that in the process of noise monitoring,the noise does not exceed the standard but it is truly disturbing phenomenon,which is enough to prove that only with noise decibels considered in the acoustic environmental quality of residential area is not scientific.Beyond that,we lack of environmental monitoring data in the design stage of residential area as the basis,many designers are also lack of consideration of acoustic environment in the market conditions.This paper aims to explore some other method and means of the evaluation and improve of the quality of acoustic environment in residential area except for that has commonly used in noise monitoring,which can provide reference for the design of residential areas.The main contents of this paper are:analysis of the current situation of domestic and foreign residential sound environment,and sums up the existing problems.Then,starting from the basic theory of environmental noise,acoustic environment in residential district,I firstly described the effects of city environmental noise on residential acoustic environment and the hazards of noise on the human body,then further reveal the residential sound environment problems and optimization method.This paper analyzed the acoustic environment of Zhengzhou jingcheng time square,described mainly from the regional environmental noise and traffic noise,noise of social life aspects.Finally,analysis the acoustic environment pollution status and existing problems of residential area after the completion of the simulation through on-the-spot investigation,software,thus put forward the feasible optimizationmethod of noise pollution.
