Reply To: What is the reason of Absorbtion Coefficient too small or zero on Impedance Tube Simulation?

What about Sound Transmission Loss?
If I tried simulation of Sound Transmission Loss, it would be another concepts as below. In this case, I think displacement, acoustic and physical region should be used. Do you have an suggestion about boundary condition or material property(such as JCA). Can you share an example for it? It should be different from absorption concepts.
Thank you.
