Default Sound absorption for speaker simulation

Estorki is on a distinguished road
I am currently modelling a speaker, analysing the resonant frequencies, sound pressure and sound velocity.

In general speaker design, materials like fibre glass foams are introduced inside the speaker to minimice the resonances.

I have done good progress but I am still struggling with one are: Sound absorption material.
I tried to replace the internal air of the speaker with an Ansys material called "Foam, glass" but then I can not select the volume as Acoustic Region.

How can I assign sound absorbing properties to an air volume for acoustic analysis?

Very much appreciate you help.
