摘要
在分析局部通风机结构与噪声特征的基础上,通过噪声声谱测定实验,选择微穿孔板结构作为局部通风机降噪的手段,结合实际对其应用效果展开分析。结果表明,微穿孔板结构在局部风机中的应用具备良好的降噪功效。
Based on the analysis of the structure and noise characteristics of local ventilator, the acoustic spectrum of noise was tested with the structure of micro perforated plate chosen as the method for noise reduction of local ventilator combined with the actual effect Of its application. The results showed that the application of the structure of micro perforated plate had good effect for noise reduction.
