Apparently you're correct. I find that just by engaging the 70hz
rolloff switch, it drops the noise floor by about 5db. Fooling with eq
drops it even more. This seems promising. I'll be curious to see how
close I can get toward my goal just by tweaking the eq & optimizing
mic placement.

You got the air conditioning turned off and all the appliances shut down?

A/C is off, as well as the breaker box next to the air handler -
already went through that drill a while back trying to figure out what
gear was making the faint buzzing noise.

The refrigerator being on or not doesn't seem to make any difference,
it's 2 rooms away - the sound would have to go through 2 walls plus
the sound booth wall which is built exactly the same way as the house
walls.
