Thank you for the link and the comments, which are well taken. Yes,
certainly I would need to calibrate the mic separately to determine
sensitivity, and that is more difficult, especially to obtain accuracy
over a wide frequency range.

The manufacturer data often lists self-noise as a single number in
dB(A). I think ITU-R 468 would be better
http://en.wikipedia.org/wiki/ITU-R_468_noise_weighting
but what I am really interested in is the actual sound of the noise
and its frequency spectrum.  I am also not convinced that all
microphones of a given model have exactly the same amount or character
of noise.
