宽频带阻抗复合消声器的设计和应用

Broad-band impedance composite muffler design and application

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 。

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.
