perforated impedance models

[AhmedGalal]

Hi there,

I'm making a research on the acoustic properties of perforates so i need to collect as much as i can the previous impedance models

so plz if any one know where to find a reference of these models

ill appreciate it

tnx

Prof A. Selamet, Department of Mechanical Engineering and The Center for Automotive Research,The Ohio State University, Columbus, Ohio has a good amount of publications on perforated acoustic impedance.
