How to bond two panels together in simulating sound waves in the coincidence region

I am trying to simulate sound waves hitting two flat panels, which is build upon the Tutorial Sound Transmission Loss in a Concrete wall. I am trying to study the behaviour of the coincidence effect by modelling different panels. My model has 3 blocks, 2 of them are MDF panels and 1 is an air domain block with perfectly matched layers.
How do I set two 4.5mm thick panels to be "glued" together so that it behaves like a single 9mm thick panel?
