摘要
围绕长隧道内声场特点、预测方法和控制方式,结合国内外学者研究情况,首先介绍了隧道内交通声场的基本特征,然后从数值方法、统计模和实验预测对交通预测方法进行了综述;最后对主被动降噪和频率优化3种声场优化途径进行了评述。
This article analyzes the current research progress around these three aspects.Focusing on the characteristics,prediction methods and control methods of sound field in long tunnels,combined with the research situation of domestic and foreign scholars,this paper first introduces the basic characteristics of traffic sound field in tunnels,and then summarizes the traffic prediction methods from numerical methods,statistical models and experimental prediction;finally,three approaches of sound field optimization,namely active and passive noise reduction and frequency optimization are reviewed.
