I've had once experienced a power cable that made strange noise when you
moved on the other side of the room which had a massive concrete floor:
the wire was broken inside it and - normally if it looses contact by an
amount small enough to create a spark gap and small enough to be caused
by someone shift the wight from one foot to the other I would have
expect this to wield the two halves together again. But this one time
that didn't happen until the cable started smoking.

But you are right: This kind of setup produces not only electrical, but
also acoustical noise - which wasn't too bad in my case as it made sure
I will find the problem before it starts a fire.

Kind regards,

 Gunter.
