The difference between Poroacoustics and Poroelastics

I have to simulate the sound transmission of the foam which statch on the earphone, but I noticed that COMSOL has two poro-material node, one is the poroacoustics and poroelastics. I wondering that if I have to consider the compressed foam which represented that the earphone clamp on human's head, which node should I choose?

It depends on what you are trying to achieve. If all you are interested in is the acoustics, the poroacoustics could probably suffice, if you can fit the values to the compressed state of the foam. If the mechanical properties of the foam influence the output that you are looking for, then you might need more complex models that include the elasticity of the foam.
