DC is not audible.
It would probably sound like one loud THUMP, and then silence. So
THAT'S
audible.

Actually, the thump would be caused by the change in signal from its old
voltage to its new one (ie: the transition from 0v to 12v). This would not
be DC, but a momentary AC riding a DC level.
How's that for nitpicking? :-p
