What are some good practices to use in calibrating one mic with another calibrated mic?
Assume mic sensitivity is not important, only frequency response is.
Some things I wonder about are:
Does it matter what kind of speaker you use to compare the mics?
How full range should the speaker used be?
Does gating matter?
Does stimulus type matter?
Any input is appreciated.

You'd be comparing the response with the mics pointed at a certain angle, eg 0 or 90 degrees. If you include reflections then the directivity of the mics may interfere with the response plots.

Most measurement mics are pretty similar up to about 1 to 2K and it is from there that they deviate the most other than at quite low frequencies.
