In PCB's and such (like a radio) the frequencies are much, much higher, so its absolutely impossible for a human being to hear them. And wtf would he hear from a car? Its operating on DC current.

It's not a hum for sure. He may be insane, but I assume he knows the difference between a hum and a screechy high-pitched thing

Maybe he does have tinnitus? Never thought of that... I've never had it so I don't know how high pitched the ringing is... I'll have to ask him.
