由南京大学和南京前卫电子仪器厂共同研制成功的NN-1型噪声自动监测仪于1986年11月10日由江苏省环保局主持在南京通过技术鉴定,参加鉴定会的有20个单位,27名代表.NH-1型噪声自动监测仪主要用于环境噪声的自动监测,可以测试统计声级(L_5、L_(10)、L_(50)、L_(90)、L_(95)、L_(99))等效声级(L_(eq))和标准偏差(σ)等,能实现环境噪声监测的采样、数据处理、显示和打印的自动过程,测试结果与丹麦B＆K公司噪声级分析仪一致.该仪器数据处理部分采用PC-1500型袖珍机,在线路设计和元件选择上
NN-1 noise automatic monitor jointly developed by Nanjing University and Nanjing Qianwei Electronic Instrument Factory was successfully passed the technical appraisal by Nanjing Environmental Protection Bureau on November 10, 1986, with 20 units participating in the appraisal meeting. 27 Name Representative .NH-1 type of noise automatic monitor is mainly used for automatic monitoring of environmental noise, you can test the statistical level (L_5, L_ (10), L_ (50), L_90, L_95, L_ 99)) equivalent sound level (L_ (eq)) and standard deviation (σ), which can realize the automatic process of sampling, data processing, displaying and printing for environmental noise monitoring. The test results are consistent with the noise level analyzer of B & K in Denmark . The instrument data processing part of the PC-1500 type pocket machine, in the circuit design and component selection
