It doesn't go through the walls... it vibrates the floor, then the floor

You may not even hear it, but put your fingers out and lightly rest them
on a tabletop and see what you can feel.

Whatever the refrigerator may be putting out isn't registering on the
level meters - i.e. plugged in and running or unplugged makes no
difference in the highest level recorded when recording ambient sound,
so in this case it doesn't appear to be a significant factor.

Both mics are shock mounted and of course, the stands are sitting on
carpet and padding, whatever added benefit that is.

So, a "floating" floor really makes a big difference?

About what frequency range is considered low frequency noise that
you're referring to?
