Acoustic Dipole Point Source Power

I have the following scenario I want to simulate:

I know the expression for the pressure at any point, given the distance vector between the point and the source.
I think I can get the acoustic power of my source , by integrating the pressure around a closed surface and dividing by the acoustic impedance (right?)

P = p²/z

The thing is I'm a bit confused from what the Acoustics Module Manual says. It says the dipole source is defined by q_d, with units N/m³.
But when I create the dipole source inside Comsol the parameter it asks for is Free Space Reference Power (RMS), in Watts.

How should I proceed from the information I have to a realistic simulation?

Thanks
