Perhaps the truck produces some noise he hears, but we can't? Haha I can't hear crap without my HAs, I miss a lot of sounds.
I know what you mean. I have worked around heavy equipment enough years to think my hearing isn't near as keen as it used to be.
Let's hope he can hear any mechanical problems before they get worse, lol!
I think I just came up with a new job for Hans.
