Capsule Circuit Model?

[Matador]

Is an AC voltage source in series with a small cap (~50pF) good enough for SPICE simulation purposes?  What is a good value to use for the AC signal magnitude for various LD and SD capsules?

In the LTspice user group, http://tech.groups.yahoo.com/group/LTspice there's a model for an electret capsule. Might want to check it out.

The LTSpice electret model is useful to replace the generator in a sim, but has nothing in common with a condenser capsule.
The 40-50pF (LDC) or 10-12pF (SDC) cap in series with a 10mV generator (for 94dBspl) is good enough for simulation.

Access to what?
