摘要：
Micro-perforated panels have been used for duct silencing for several years and are gaining popularity. This paper presents equations for predicting the sound attenuation of micro-perforated panel silencers. It also presents guidelines for silencer geometric parameter selection to improve silencer performance. The guide-lines are taken from both silencer tests and theoretical analyses.
