宽频带阻抗复合消声器的设计和应用

Broad-band impedance composite muffler design and application

摘要: 根据风机房进风口噪声的频谱特征和现场噪声的分析,给出了低频、宽带阻抗复合消声器的设计方法,通过实际应用证实了宽频阻抗复合消声器的消声效果。

Abstract: Based on the spectrum characteristics of the noise from fan room air inlet and an analysis of on-site noise,a design method for low frequency,broad band impedance composite muffler.Practical application confirms the noise muffling results of the broad band impedance composite muffler.
