摘要： 用B&K 2250手持式精密噪声分析仪，对跨坐式独轨列车运行时产生的噪声进行信号采集及分析，得到其传播规律、频谱等特性，并与普通轮轨噪声进行对比。结果表明重庆独轨列车低频部分声能量较小，对比普通的B型轮轨列车，跨坐式独轨列车的噪声值明显较低。

Abstract: B&K 2250 handheld precision noise analyzer is used to measure the noise data of cross-type monorail train, then the noise propagation pattern and the spectrum are gained as well. The results show that low-frequency part of the energy of the Chongqing monorail train noise is small. Compared to that of B-type wheel-rail train, the noise level of cross-sit-monorail train is significantly lower at the same speed.

Key words: acoustics , noise characteristic , contrast , cross-sit- monorail train
