英国CRTN道路交通噪声预测模型在中国的适用性研究

Evaluation of the Performance of the UK CRTN Traffic Noise Prediction Model in China

基于道路交通噪声990 h监测数据,对英国CRTN模型中源强计算模型在中国的适用性进行了验证。试验结果表明,理论计算与实测结果之间平均仅相差0.57 dB(A),CRTN源强预测模型在中国可以可靠地预测道路交通噪声。

Based on 990-hour road traffic noise data collected by automatic noise monitoring equipment,this paper evaluates the performance of the Calculation of Road Traffic Noise（ CRTN） prediction method in China. The experimental result shows that the average difference between the theoretical and the measured results is only 0. 57 dB（ A）,indicating that the CRTN prediction model is reliable and accurate for traffic noise prediction in China.
