利用计算机预测噪声对环境的影响,在国外已有不少文献报道和实例。在我国这项工作起步较晚,目前尚处于开发阶段,虽已有一些单他在工厂设计之前进行了噪声预测,但都是采用A声级的类比方法·尚未采用计算机预测,更未采用分频计算的预测方法。 The use of computers to predict the impact of noise on the environment has been reported in many foreign literature and examples. This work started late in our country and is still under development at present. Although he has made some noise predictions before the factory design, all of them are analogies using A sound level. Computer-based prediction has not been adopted, Prediction method of frequency calculation.
