Research On Noise Prevention Spacing Between Adjacent Teaching Buildings In Primary And Middle Schools

Although the State Council issued relevant documents in September 2012 to adjust the policy for the withdrawal and merger of rural primary and secondary schools,China’s primary and secondary schools have entered the “removal and merge era”,The number of primary schools can find that the impact of the "era of merger" still exists.Moreover,when the overall number of primary and secondary schools shows a downward trend,the number of primary and secondary schools in urban areas shows an increasing trend,and the largest growth rate is in urban areas.In urban areas,the increase in the number of schools and students also includes the land area,building area,and comparable floor area ratio of primary and secondary schools.While all aspects of urban schools are increasing,our country has also put forward guidelines for economical campuses.In a frugal campus,land saving is a very important aspect.However,for primary and secondary schools,the rigid requirements of the relevant items in the specification for the distance between the teaching buildings reduce the possibility of saving land and limit the space for the development of primary and secondary schools.This article first uses a summary and comparison method to conduct an inductive analysis of noise-related specifications in primary and secondary schools.It is believed that there is a certain continuity between the two versions of the code,but the lack of data update may cause the original data to be unsuitable for the built environment Situation;then through the measurement of the distance between the adjacent building and the indoor noise value,the typed study of the spatial position relationship,and the students’ survey of the feelings of the noise director,the standard rate of the primary and secondary school building spacing was reached,and the distance was explored The relationship between the value and the spatial position,and the noise value of the classroom and the user’s experience during actual use.After that,the type and simulation of the horizontal and vertical positional relationship of the teaching building’s noise propagation are different for the two basic spatial positional relationship teaching buildings The influence of the positional relationship on the noise propagation was explored,and the space types and building space composition forms that were most conducive to noise attenuation were obtained.Finally,the active noise reduction methods that can be used in primary and secondary schools were reviewed and the levels were explored by computer simulation The relationship between adjacent teaching buildings that meet the indoor noise requirements Spacing value.Based on the research in this article,the author summarizes the noise interference and noise prevention between the adjacent teaching buildings in urban primary and middle schools,explores the influence of the different positional relationships of the adjacent teaching buildings,and the layout of the teaching buildings on the spread of noise between the adjacent buildings.The active noise reduction methods that can be used on the campus of primary and secondary schools simulate the minimum noise prevention distance that can exist between adjacent teaching buildings.The original intention of the design specification is to ensure the basic needs of users.Only specifications with quantitative indicators of data can become the standard for judging design,and can ensure that the specifications can be effectively and clearly implemented.But design itself is a complicated process,and too many quantization constraints will make it lose many possibilities.For example,the problem of noise prevention can be solved through various means such as sound-absorbing materials,window insulation,and building layout optimization.However,due to various reasons,the standard has chosen the easiest way to control the distance between teaching buildings.The noise separation distance in the current specification is introduced.This paper attempts to prove to readers that the noise distance value continued from the 1986 "Code for Design of Primary and Secondary School Buildings" has a better value by using field measurements of classroom indoor noise values,surveys of students’ use experience,and simulation of minimum distance methods.Sound insulation technology is a bit too large for modern teaching buildings.At present,the country advocates a land-saving campus,and the building has better and more sound insulation and noise reduction techniques.Under the premise of ensuring that the teaching activities in the classroom are not affected by noise,there are various possibilities for the distance between teaching buildings.
