摘　　要：随着噪声自动监测技术的不断完善和广泛应用,我国城市环境噪声自动监测系统相继建立。但由于目前国家缺乏相应的技术规范,对于噪声自动监测仪器的校准周期,以及噪声自动监测系统的质量控制与质量保证,各个城市均处在摸索研究阶段。通过对国内应用的几种主流环境噪声自动监测系统进行运行测试,掌握其运行稳定性、测试准确性,通过定期开展标准声源测试检查计算不同仪器在同一定时间内的相对偏差,以评价不同设备运行稳定性,提出测试的最佳校准周期。With the continuous improvement and extensive application of automatic noise monitoring technology,automatic monitoring system of urban ambient noise in our country has been established one after another.However,due to the current lack of appropriate technical specifications in the country,various cities are in the groping research stage for the calibration cycle of automatic noise monitoring instruments and the quality control and quality assurance of automatic noise monitoring systems.Through several major domestic environmental noise monitoring system to run the test to master the stability of its operation,test accuracy,through regular testing of the standard sound source to calculate the relative deviation of different instruments in the same time to evaluate the different Equipment operation stability,proposed the best test cycle calibration.
