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?
