Cool, thank you for the link. To measure and correct for the frequency response of the microphone, can't you just play a range of known frequencies that each have known power levels, and then measure the gain/loss in power level that gets recorded by the mic, and then solve for a filter that gives you unity gain on the mic? I assume that you'd have peaks in the frequency response around the natural resonance and harmonics of the mic, and you'd basically just be adjusting for those.

That's how the process works, but it's more complicated than you'd think. The room a speaker is in changes the overall frequency response. Speakers aren't flat, either. There are ways to get past these obstacles, but it can be difficult and expensive to get right. Going to the the world of infrasound just increases the complexity.
