How big is the restoring force compared to the force due to pressure?
I'm assuming significantly smaller, so that ignoring it can still give
you a workable first-order approximation. Or is that not true?

There are two useful choices for the mass/ compliance resonance,
above and below the passband. The usual choice for open (pressure-
differential sensitive) microphones is below passband and the usual
choice for closed (pressure sensitive) microphones is above
passband.
