公路交通噪声预测的神经网络模型

摘要

利用多条国道、省道公路交通噪声的实测数据，建立了一个公路交通噪声预测的神经网络模型，能够同时预测公路交通噪声的等效连续声级、统计声级和标准偏差，预测值和实测值基本相符。该模型为公路交通噪声的预测、治理和控制提供了良好的条件。%By using some road traffic noise mreasured data, a model of neural network for road traffic noise prediction was established, which can be used for prediction of equivalent continual sound level, statistical sound level and stan-dard deviation of road traffc noise. The prediction results generally agrees with measurement values. The model pro-vides condition for predicting, administering and controlling traffic noise.
