While it talks about MEMs mics, much of that applies to any very small
mic, and the problems of protecting the diaphragm from, yet interfacing
it to, the outside world.

Thanks for posting it, that's the first time I see actual plots of a
MEMS microphone. Can anyone explain the reason for the horrible peak
at 15k? Is is possible to linearize it to get a useful response above
10k, or does it come with extreme ringing that would make it unusable?
Always good to learn about up and coming new technologies, but for
this one I'm dusting off and waxing my ten-foot pole...
