Woodward Governor Co. ---------- From: [email protected] To: [email protected] Subject: Perforated Metals List-Post: [email protected] Date: Thursday, October 30, 1997 4:35AM Hello group, Some years ago I had a copy of a design guide for perforated metals and how to calculate attenuation factors at various frequencies. This guide included information on different types of metal, thickness, lamination and hole size/pattern. I am able to locate websites that address airflow issues and effective cross-section but not emissions. Can anyone point me in the right direction?
