Thank you for your response. That is very helpful since I do have a limited number of listening nodes. I've performed some simulations to test the reciprocity (swapping the source and receiver locations). As expected, I got perfect reciprocity when no structure was included in the simulation. However, when I included structural coupling I did not see reciprocity in my results (Acoustic pressure at the receiver location was different when the source and receiver location was swapped). Is reciprocity only true in the case without structural coupling? I will continue to review my simulation setup to see if perhaps that is where I made a mistake.
