实测表明,在离轴流式鼓风机旁1米处A声级可达110分贝。最有效而又简便的控制方法是采用隔声罩,将声源—鼓风机全完封闭起来,阻止声能传入工作环境。这种噪声控制措施的特点是:降噪效果好,结构简单,施工方便,花钱少,见效快。图1为武钢V AS9018型轴流式鼓风机 The measured results show that the sound level of A at the side of the off-axis flow blower can reach 110 dB. The most effective and easy control method is the use of noise enclosures, the sound source - the blower completely closed to prevent the introduction of sound energy into the work environment. This noise control measures are characterized by: good noise reduction, simple structure, convenient construction, less money, quick results. Figure 1 is WISCO V AS9018 axial flow blower
