摘要
基于噪声计算理论及现行多个噪声职业卫生标准,开发了作业场所噪声仿真分析及评价软件。该软件能同时实现多个作业点噪声值的预测和个体日8 h/周40 h接触等效计算,并根据计算结果完成作业人员日/周接触(噪声强度、时间)卫生评价,还可以实现噪声职业危害分级评价,以图像的形式展示作业场所噪声的分布状况。并以某发电厂磨煤车间为例进行了具体仿真分析及评价。
A type of workplace noise simulation and evaluation software was developed based on the noise calculation theory and current noise occupational health standards. The software can simultaneously achieve the prediction of noise values in multiple operating points and calculate the exposure equivalent of noise value at 8 hours in a day or 40 hours in a week. The day or week exposure（noise intensity,duration） health assessment for operators and noise occupational hazard classification evaluation were carried out according to the simulation results. The noise distribution in workplace was graphically illustrated. Finally,the noise simulation analysis and evaluation were conducted by taking the case of the coal-pulverizing plant in a power plant.
