摘　　要：噪声自动监测系统可以对噪声进行长期连续监测。通过对连续两年的北京市自动噪声监测数据进行分析表明,烟花爆竹燃放噪声能够对声功能区环境评价参数昼间等效声级、夜间等效声级及其达标率产生较大影响。尤其是1、2类声功能区影响可使等效声级提高10dB,达标率降低3%。提示有必要把节日的燃放噪声与其他噪声分开,单独分析。Noise automatic monitoring system can be used to monitor the long-term continuous noise.Based on the data over two consecutive years in a large city,noise analysis of letting off firecrackers shows great impact on the environmental evaluation parameter such as day-time equivalent sound level,night-time equivalent sound level and standard rate.Especially,equivalent sound pressure level of the first and second acoustic environment functions can make to improve about 10dB,and the standard rate can be reduced 3% percentage.It is suggested that the firecracker noise should be separated with other noise analysis.
