Noise Characteristic of Cross-sit-monorail Train

BK 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.
