I am looking to do an acoustic analysis in openFoam utilizing acousticFoam. To simulating dampening acoustic plates on walls i am looking to using the Acoustic dampening fvOption.

However i am not an expert in reading openfoam's source code and therefore i am not certain how this would interact as acousticfoam solves the acoustic pressure, while the fvOption dampens the regular pressure. Anyone got any info on how this interaction works?

you use your fvOptions to add a source/sink. In this case, since you want acoustic damping, you add a sink term to the acoustic pressure (pa). It does nothing to the regular pressure because there is no regular pressure in acoustic foam.
