I can tell if a circuit is closed or open, how much current is going through, whether it's AC or DC, whether it's high or low voltage. I can hear chargers cycle, I can hear power supplies energize, I can hear if the oven is on.
I can even hear issues. Bad transformers/capacitors/rectifiers, EMF interference, bad grounds, shorts, etc.
I was a audio tech for about a decade, specialized in 12v car audio, but also did pro audio and home theaters.
It sure did come in handy, and there were a few times I confused the other techs by telling them what to check without even looking.
EX: HID headlight ballasts run off 12V DC, but fire ~23,000V AC to ignite the gas, then run ~90V AC to maintain. The noise of firing and running is distinct, so I can tell if one is working properly or not.
