That is a tough one, Rob. There is definitely a shift in qualities between the 
two, but one does not seem to have 6dB less noise than the other. That may be 
because the subject clock and crow are on axis to the mic capsule in both, 
where I would expect the biggest difference would be for sounds the boundary 
itself is facing.  I'm going to guess that A is on the boundary, because it 
sounds like the barrier shadows some of the higher frequency content heard in 
B. Even with 50% chance to get it right, I bet I am wrong.
