External sounds audible in cockpit with engine running?

I've never flown any of the aircraft featured in Cliffs of Dover, but I've flown a North American Harvard. It's a WW2-era aircraft and you cannot hear a thing over the engine sound other than the radio speaker in your helmet. Perhaps Merlins, DB601's, and Jumos, etc. are significantly quieter in the cockpit than P&W Wasp radial engines -- that I wouldn't know.

That said, I didn't vote since there was no realism option offered in this poll. Otherwise, it's a fair question IMHO.

EDIT: Brian Lane in his book "Spitfire!" comments that he can hear near-bursting AA fire - something worth consideration in CoD.
