I honestly have no clue how to answer. My last hearing test was part of my DOT physical in 2003? They put me in a sort of phone both box with headphones on and told me to push the button when I heard the sounds in the headphones.

LOL I had too much trouble hearing the phones ringing in other rooms, people walking down the hallway talking to clearly hear the sounds. Their opinion was I had suffered some hearing loss in my right ear. 30+ years of sitting next to a turbo charged diesel engine or the sound proofed box wasn`t exactly that?

Maybe so, maybe no?
