摘要
炼厂电机噪声是污染厂外环境的主要声源之一,采用新型的微孔板结构隔声罩,可降低电机噪声18.5dB(A),并具有易于加工、结构轻、易于清洗,不会造成二次污染的优点.
One of the main noise source of polluting out of factory is motor noise.The new type sound proof plate of mini-bore structure was used.It can decrease the motor noise 18.5dB(A).It's advantage is light structure,easy processing and cleaning and no second pollution.
