Simulating Research On Influence Of Road Noise On Residential Quarters

With the rapid development of urbanization in China,traffic pressure has become increasingly serious.Traffic noise pollution has become an important factor affecting the urban environment,and it has also become an unavoidable issue in the process of urban health development.How to effectively reduce the impact of road noise,and build a quiet and peaceful residential area is a difficult problem facing the current urban development.To explore the reasonable arrangement of urban living space and reduce the impact of noise is the trend of urban residential development.This article takes the residential area of the old city of Ganzhou as the research object to study the influence of traffic noise on the residential area,analyzes the combination of the residential area layout and the monomer noise prevention method in response to road traffic noise,and improves the acoustic environment of the residential area.By statistically summarizing the traffic flow information of 56 residential areas and 27 roads in the old city area,a 2-hectare residential area with a floor area of 6 hectares and a floor area ratio of 1.09 is summarized,along with the corresponding trunk,secondary stem,Branch roads and other road noise characteristics.Using CadnaA software simulation,by listing the results of noise in different spatial arrangements on the virtual plot,using determinants,enclosures,point groups,and hybrids as classifications to compare the pros and cons of different spatial arrangements to find poor results.Better layout of buildings in acoustic environment.In the determinant layout,the parallel determinants of the same building density and floor area ratio are better than staggered columns,and the declining noise reduction effect is good.The distance between the expanded roads and buildings is only reduced by 2 decibels per 10 meters,and the uneconomic results are not satisfactory.Board-point combination better than pure point layout and other conclusions.While searching for noise reduction strategies,we chose the typical residential area in the old city as an example to explain the feasibility of various schemes,and put forward some suggestions for noise prevention in the construction of individual buildings and in the population.
