You'll find detailed information (the formulas and graphs) on the distance
models in the OpenAL Specification and Reference linked at openal.org.
Correcting the panning situation that you describe is likely a matter of
setting the listener orientation, and once you look over the available
models it should be straightforward to get the desired behavior.
