Answer is you can't. But if you can hear it, they should be able to. Don't get all psyched out before you talk to them.
That's what I was afraid of. It's just one of those things you hear in the back of your head. You can sit there and not notice it then all of a sudden your brain will pick up on it, and then it becomes annoying. I guess I'll give it a try. Maybe I'll get a mechanic with really good hearing.
I wish I could find a way to isolate the noise somehow. Turning the radio up helps to hear it better, but it's still subtle and mixed in with other radio noise, and somewhat intermittant.
