City Environmental Noise On Residential Areas And The Effect Of Optimization Method Research

Along with our country of old city transformation and the construction of new urban unceasing advancement, and town to change construction pace accelerate, city population growing, residential area also is in increase ceaselessly. At the same time, along with the improvement of people's living standard, various living facilities have gradually entered the home, accompanied by the residential area noise pollution has become a serious problem. While residential acoustic environment is good or bad, it will directly affect the residents' quality of life and physical and mental health. In the long-term noise pollution of the environment will make people deaf, decreased visual acuity, memory loss, insomnia, debilitating symptoms, sometimes serious hypertension, heart disease, depression, mental disorders, endocrine disorders and other. Especially for some good physical condition or older residents, noise caused by injury cannot be resumed. Therefore, residential district noise pollution control is necessary and urgent. China's noise related to standards and regulations lag behind other developed countries, no matter in the design of residential area the stage or in the late in the regulatory process, simply to noise decibel number for evaluation of acoustic environment in residential district, there are certain one-sidedness. In addition, our country lacks internal acoustic environment in residential area detailed noise standard, in the evaluation of residential area of internal acoustic environment, more general, not specific, also not true, objectively reflect the quality of acoustic environment in residential district. In addition, our country community in noise monitoring process in the presence of noise standard but disturbing phenomenon, enough explains only with noise DB level to the evaluation of acoustic environment in residential district, is not scientific. In addition, in the residential district design phase lack of environmental monitoring data as basis, designers in the design of the lack of residential noise considerations.This thesis aims to explore, in addition to the more commonly used noise monitoring, the other on the acoustic environmental quality of residential area evaluation methods and means, but also for the residential district design stage to provide reference. The main content of this paper is: the basic concept of residential acoustic environment narration; analysis of environmental noise on residential areas influence and harm to human body; analysis at home and abroad and the the Inner Mongolia Autonomous Region residential acoustic environment, and sums up the existing problems; urban center in Chifeng city as an example, through questionnaire survey and interview way residential area residents about noise pollution level of understanding about their lives, interference is the main noise source which, body of adverse reactions as well as the residential acoustic environment noise pollution problems suggestions and ideas. Based on the survey data, processing and analysis, put forward Chifeng city to the current residential acoustic environment problems, such as the design of residential acoustic environment, lack of phase lack of consideration of residential indoor noise standards, and low frequency noise on the residents of the interference are ignored, the residential area environmental noise pollution, the lack of a unified management. Finally, can take the optimization method. This paper is the study of the noise decibel rating with the exception of acoustic environmental quality of residential area outside the evaluation method, the residential area residents' subjective feelings as the evaluation index, reflects the people-oriented concept of the building. In addition, the response of the residents of relatively centralized problem analysis, put forward optimization method, the acoustic environment in residential district design phase and late improvement there is reference value.Residential acoustical environment will have a direct relationship to the living of the happiness index, while the acoustic environmental quality of residential area evaluation in addition to the application of state issued a series of standards, laws and regulations, but also consider the subjective feeling of living area residents. In the acoustic environment in residential district planning and design stage should be more residents to the living environment of demand taken into account in the design of residential area, thereby effectively improving the quality of life for residents.
