"It turns out that the dominant cause of the susceptibility was a pin 1
problem!"
It's not only microphones. Our lab's data acquisition cards and
breakout boxes have a pin 1 problem as well.
Very popular manufacturer of such things so I'm sure we're not the
only ones... but we are using a couple of hefty motors driven variable
frequency drives in the vicinity of the sensors and acquisition
system.
We had a heck of a time cutting down the noise until we figured this out.
It's a major problem, all this stuff in metal boxes that do absolutely nothing!
