Analysis of Acoustic Environment Quality in Guang'an City
Guang'an city is located in the northeast of Sichuan province and is also the closest city to Chongqing city,and the effectiveness of building Guang'an city into a demonstration zone for Sichuan province-Chongqing city cooperation is closely related to the overall environmental quality of the local area.Taking Guang'an city as the research area,the monitoring data are collected on regional noise,functional area noise,and road traffic noise from 2021 to 2022,the characteristics of sound environment quality are analyzed,and the sources of noise are clarified.The results indicate that the overall quality of the regional acoustic environment has remained stable with some decline,with a more significant decrease in the area covered by first level noise.The daytime noise in the functional area can achieve 100%compliance,and the nighttime noise all met the standard in 2021,with a compliance rate of 87.5%in 2022.The compliance rate of daytime noise in road traffic in 2021 was 100%,and in 2022,the environmental quality of daytime noise in road traffic had decreased,with a compliance rate of 85%.Overall,the main sources of noise in the sound environment quality of Guang'an city are social life noise and road traffic noise.
