澳门半岛交通噪声模拟与控制研究

交通噪声是澳门半岛最主要的环境噪声源。本研究在国际上通用的交通噪声预测模型STAMSON的基础上 ,根据澳门半岛封闭型道路的特征 ,建立了封闭型道路交通噪声计算机预测模式 ,经过实测数据的验证 ,模型预测结果达到了令人满意的精度要求。利用建立的交通噪声预报模式 ,计算了澳门半岛不同类型道路的交通噪声水平 ,定量评价了道路交通噪声的污染状况。最后 ,根据澳门半岛交通密度高的特点 ,提出了新的环境噪声标准建议 ,并给出了逐步改善环境交通噪声的主要措施

RESEARCH ON SIMULATION AND CONTROL OF TRAFFIC NOISE IN MACAO

Traffic noise is the main source of environmental noise in Macao.On the base of the STAMSON model that is popular used in world,according to the character of close roads in Macao,a Close Road Traffic Noise Forecast Model is built.Through the validation of monitoring data,the result precision of the model is satisfied.Using this model on the traffic noise level in the different type roads in Macao,The pollution level of traffic noise is assessed quantitatively.Finally a new standard of environmental noise is recommended and the major measures of improving the noise pollution gradually are also given on the base of the high traffic noise density in Macao.
