摘要
本文根据几何声学原理，利用一维有限长线声源模型，模拟预测了高架轻轨交通辐射的噪声在沿线不同远处、不同高度处场点上的强度。为我国正在兴起的轻轨交通系统规划建设中合理采取防噪、降噪措施提供科学依据和手段。
Based on the principles of geometrical acoustics and uesd one dimensional limited line sound source model,the intensity of noise is simulated and predicted,which caused by the light rail transit (LRT) over head,in different distance and high.This paper may offer a scientific basis and means to make a reasonable program of light rail traffic system in order to protect from and reduce the noise of LRT which is rising in our country.
