Dongfeng _4 diesel locomotive main driving force for the 16240ZB diesel engine, test station vibration noise generated when the impact on the health of workers, especially for hearing impairment is more prominent. This paper mainly investigates the damage of noise to workers’ hearing, the result is as follows. First, the diesel test station of the general situation and sound source analysis Experimental station mainly by the diesel engine room, control room, auxiliary room, pump room and other components, separated from each other. A diesel test time of 108 hours. Diesel engine fitter and mechanic fitter mainly observe the diesel engine and supercharger test situation, and troubleshooting at any time. Driver in the soundproof control room, through the two layers of windows on the test diesel far
