I think the problem is you can't hear anything with your engine on while flying thousands of feet over the field. Same reason you can't hear an enemy plane's guns until he's really really close -- because there's too much noise drowning him out.
I know that when people man the soft ack guns, they make noise. I've seen it personally. Auto ack, I thought did as well. 
Nah, you are hearing the manned ack chattering.
