摘要
应用德国《道路噪声防护导则》(RLS 90)中的预测计算方法对道路辐射噪声进行预测,为声屏障的设计提供充分的理论依据并简化声屏障声学计算过程,形成模块,便于在公路声屏障设计中运用。
The prediction and calculation methods in 《German road noise protection guide 》（RLS90）are used to predict the radiation noise of road, to provide full theoretical basis for design of acoustic barrier, to simplify acoustic barrier calculation process and to form modules which are easy to be applied in acoustic barrier design of highway.
