| Abstract: | The noise monitoring on the passenger trains of Urumqi-Chengdu indicates that in general the noise equivalent sound level A in carriages is below the standard level (TB1932-87) issued by the Railway Ministry. But in the case of obsolete carriage machine, complicated railway conditions, railway tunnels and narrow valleys, the noise equivalent sound level A in carriages can reach to 74.9-84.6dB(A), the highest noise exceeds the standard level 9.6dB(A). The noise of the whole course exceeds the standard level 2.2dB(A). |
