Evaluating multiple MEMS microphones

Hello,

I need to evaluate multiple MEMS microphones to weed out which one is the best for my application. I am looking for some ideas on how to do this. I can get a noise floor for each microphone and also characterize each microhpone in terms of frequency response. Other than that, what would others do to evaluate the performance of a microphone. My application requires frequencies from 20Hz - 2KHz.

Thank you for any ideas.
