What Physics one should take in COMSOL for SOUND TRANSMISSION LOSS of membrane with the added mass?

10 July 2023 0 2K Report

I have taken 1) pressure acoustics, 2) membrane, and 3) solid mechanics.

I have used three multiphysics 1) membrane and solid mechanics for membrane and added mass interaction, 2) acoustic structure and solid 3) acoustic structure and membrane.

Is it correct?
