Dr. Stephen Drasnin should be disqualified from performing DOT tests on potential drivers. I failed my hearing test. Yes, I may be tone deaf, but he didn't even consider the possibility that people can wear hearing aids if need be. He relied completely on the audio device to fail. He didn't even mention the "whispered voice test". It is a part of the testing procedures. You first conduct a "whispered voice test" then upon failing that, you use the audiometric device.
