trust me, an open dooron a cherokee isn't easier to hear with
an ANR headset. First clue I had was a cooollllldddd breeze.

I had the opposite problem. While climbing to cruising altitude,
one of my exhaust tubes broke at the flange on the cylinder.

I had an exhaust pipe break. I could hear a clanking. I took off the
headsets so I could hear it better, and then I couldn't hear it over the
rest of the engine noise. Putting them back on I could hear the clank
again.
