Noise Status and Control Measures of Sound Environment Functional Areas in Main Urban Area of Luzhou City From 2021 to 2023
This paper uses the noise monitoring data of the sound environment functional areas in the main urban area of Luzhou City from 2021 to 2023 to analyze the noise characteristics and changing trends of various sound environment functional areas.The results show that the overall sound environment quality in the sound environ-ment functional areas of Luzhou City is good,and the noise pollution at night is more severe than during the day;The daytime and nighttime compliance rates of Class 1,Class 2,and Class 3 functional areas,as well as the day-time compliance rate of Class 4a functional areas,are all above 90％,while the nighttime compliance rate of Class 4a functional areas is only 25％;The daily variation curve of the equivalent sound level of noise in each function-al area of the sound environment generally shows a bimodal pattern,and the trend of change is closely related to the daily life,travel and production activities of urban residents,as well as the season.It is recommended to do a good job in environmental noise pollution prevention and control in the main urban areas in the future by reasona-bly planning the road network layout,accelerating the pace of enterprise entry,optimizing the construction period,strengthening noise complaint law enforcement,and promoting automatic noise monitoring.
