| With the progress of the society and the development of the economy,people’s requirements for the living environment are getting higher and higher.Environmental pollution not only imposes certain restrictions on social development,but also causes troubles to people’s life.Among them,noise pollution has become an environmental problem of universal concern in the society.As one of the main noise sources in the city,the heat source plant has the characteristics of numerous noise sources,wide noise frequency range and high intensity.Therefore,it is necessary to study noise control in heat source plants,and the research results are also of reference significance for other types of factories.This article will noise control of shenyang station heat source in shenyang,liaoning province as an example,based on the voice of noise characteristics,based on the noise source and noise frequency of shenyang station heat source factory survey analysis,use the method of combining the field survey and field interview,from the aspects of equipment,site planning and architectural design from three aspects of noise reduction design,explore the effective method of noise control for heat source plant.The specific research contents are as follows:Firstly,in the first part of the paper,the background of the research on noise control of heat source plant is introduced,and the basic concept of heat source plant,the current noise disturbing standards in China and relevant laws and regulations on noise control are explained.This paper summarizes the research status of the sound environment evaluation system and noise reduction technology for green buildings at home and abroad.This paper analyzes the research basis and research methods.The second chapter studies and analyzes the sound characteristics of noise,sorts out the calculation methods of noise intensity level,sound pressure level,sound power level,noise reflection,projection and refraction,and on this basis extracts the sound insulation principle,conditions and results of noise superposition,and the degree of sound pressure attenuation in the process of sound transmission.The third chapter mainly discusses the current situation of the construction engineering and equipment characteristics of the heat source plant of shenyang railway station.Starting from the project background,the overall layout,building functions,related equipment and building structure are expounded,and the advantages and disadvantages of the current heat source plant in the functional structure of shenyang railway station are summarized.Secondly,the equipment characteristics and operation mode of the heat source plant in shenyang station are introduced to provide basic data for the subsequent noise reduction methods.In the fourth part of the paper,the source of noise in the heat source plant of shenyang station is analyzed.In addition,the propagation mode of noise in the heat source plant is studied.According to different propagation media,noise control can be carried out on the path of noise propagation,which increases the feasibility of noise reduction.According to the investigation and research,the basis of the first four chapters in the fifth chapter put forward in view of the noise control of shenyang station heat source method,according to the characteristics of the noise from the equipment,the overall planning and architectural design three aspects to explore and study the urban planning,architectural design and the link between noise and for future urban noise control idea and foundation. |
