韶山Ⅰ型电力机车司机反映,退乘后自感耳呜、疲乏、睡眠不佳。因此,我们对该机车运行中司机室的噪声进行了测定。结果,司机室稳态噪声:平原区、丘陵区短轨分别为79～82、83～87dB(A),平原长轨区为77～78dB(A),平均为80dB(A)。其中机车运行速度相同时,一般平原区比丘陵区低
Shaoshan Electric Locomotive driver reflects the self-evoked tinnitus, tired, poor sleep. Therefore, we measured the noise of the driver’s cab in the locomotive operation. As a result, the steady-state noises of driver’s cabs were 79 ~ 82,83 ~ 87dB (A) in the plains and hilly areas, and 77 ~ 78dB (A) in the long-rail plain with an average of 80dB (A). Where locomotives running at the same speed, the general plain area is lower than the hilly area
