金属結构車間是机械工厂高噪声車間之一。虽然以机械操作代替手工操作,以低噪声的焊接代替鉚接,以无噪声的液压代替錘打后,噪声有所降低,但在机械工厂內还是属于高噪声車間。金属結构車間的噪声,主要是以空气为介質的固体振动声,如錘打鋼板、鉚接,用风动工具开凿坡口,去毛刺、鏟(磨)堆高、設备振动、机械摩擦等。其 Metal structure workshop is one of the factory noise plant. Although the mechanical operation instead of manual operation, low noise welding instead of riveting, no noise hydraulic instead of hammering, the noise is reduced, but in the machinery factory is still a high noise workshop. Metal structure workshop noise, mainly air as the medium of solid vibration sound, such as hammering steel, riveting, using pneumatic tools to cut the groove, deburring, shovel (mill) heap, equipment vibration, mechanical friction and so on. its
