Acoustic Environment Study About Secondary School Based On Acoustic Comfort In Eco-campus

With the development of urbanization,the environment of the world is getting worse.Green,ecology and sustainable development has been focused with hotter and more important in the current society.Green school and Eco-campus theory are becoming the ecological problems of understanding and studying the campus environment of secondary schools in urban city.It is very urgent that we should improve the living environment and ecological quality of urban secondary schools,as well as we should develop Eco-campus.Campuses in secondary schools act as a lot of topological nodes of the whole urban morphology.It is one of the main factors influencing the ecological level of a city.Based on the Eco-comfort of Eco-capmus,the noise pollution of these schools,where are both learning and communicating spaces for adolescents,is becoming increasingly serious.A series of studies showed that the noise affects their body and mental health.Especially,in this stage,their bodies are growing and developing rapidly on the physiology and psychological,accompanying with both development and mutation.They are experiencing a sharp acquisition of knowledge and growth,as well as a crucial stage for the initial formation of the world outlook,life outlook and values outlook.Improve the quality of the acoustic environmental in secondary school,students not only achieve the harmonious coexistence with acoustic environment,but also arrive harmonious coexistence with each individual.We aim to create an ecological comfort acoustic environment of schools,what are suitable for health of body and mind for the adolescents' growth.The construction and improvement are more significant in contemporary.Adolescents act as the subject of the campus,we explore the interaction of their own and acoustic environment.Is there any difference in individual acoustic environment experience?Is it possible to actively adapt to the change of objective acoustic environment by physiological regulation,behavioral change and psychological adjustment? Especially in harsh acoustic environment.Is there any change in these data characteristics due to the diffierent noise sources?Taking as 9 representative secondary schools in Taiyuan City as study of object,the samples of the urban noise coming from traffic noise,construction noise and community noise are respectively selected for field study.We adopted literature demonstration,field measurement,questionnaire survey,statistical method,analytic hierarchy process and fuzzy mathematics methods et.al.In this paper,the samples are analyzed and studied deeply,and the evaluation index system of the acoustic environment of secondary school based on Eco-comfort is preliminarily built in a big city in China.First,this article focused on the sample selection and field visit of acoustic environment in these samples.We analysed the characteristics,campus connotation,and layout of the campus,and arrived at the need based on the adolescent cognition.And then we anlysed the data of the objective acoustic environment by main acoustics index.Furthmore,we understood the characteristics of the noise pollution and disciplinarian of these data.Based on the results of adolescent questionnaire,we commenced on the acoustic envirionment on the subjective data,and explored the correlation with objective and subjective factors.It was important that studing the effect urban noise on adolescent,annoyance degree and satisfaction of their acoustic environment et.al,and conduct quantitative analysis and qualitative research were conducted.In orde to increase the international communion of the research outcome,two ICBEN standardized survey questions with the corresponding 5-verbal scale were adopted,as a result,dose-response relationship curves of noise were construted and the characteristic on noise evaluation of Chinese adolescent was systematically analyzed.In the meantime,the noise limit simulation was done,so that the data of sound insulation and noise reducing weresupplied.In the end,the indicator system on "Eco-comfort" based on Eco-compus was built.This thesis's main work gets following achievement:1)As for the subject of the campus,adolescent,we applied cognitive psychology to subjectively study and analyze on objective acoustic environment.2)Based on the two ICBEN standardized survey questions,the dose-response relationship curves of noise were construted and the characteristic on noise evaluation of Chinese adolescent.3)The indicator system on "Eco-comfort" based on Eco-compus was built,which based on the fuzzy analytic hierarchy process.
