They didn't try and clean your ears? When I was there 2 guys didn't pass and they made them use some ear cleaning solution to see if it was only ear wax.
I was surprised I passed the hearing....gross story here, but I was impressed....In HS for a soccer physical the DR did the standard "look in your ears with the pointy thing with a light on the end" test and when he did he was amazed at the amount of ear wax I had. He said, "oh my, hold on a second" and pulled out from his drawer what looked like a tiny baby spoon. He worked it into my ear and scooped out a ball of wax that was about the size of a small marble! Awesome to look at, but amazingly gross.
Back to reality...... Good Luck!!
