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。

关 键 词:声环境评价  烟花爆竹  昼间等效声级  夜间等效声级  达标率

Abstract: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.
Keywords:Acoustic environment evaluation  Firecrackers  Day-Time equivalent sound level  Night-Time equivalent sound level  Standard rate
