Can someone explain me how I can apply/define a perforated panel in Ease?

Either the material you wan't is included in the database that comes with EASE, or you can add your own materials to the base. For that you will probably need the absorption data from third parties, institutions, books. The module used to create new materials is the EASE Material Base.

But imagine, in the case of a perforated ceiling, if I want to add, for example, an acoustic blanket, I must draw an overlay surface to the perforated panel with the characteristics of the acoustic absorption blanket?

EASE doesn't calculate the absorption coefficients of a construction, You have to know it. And then define Your material as Pedro wrote.
