Something like that scared the bejeezus out of my wife the first time it
happened to her. She'd unknowingly put her mobile next to her system
speakers, which are attached to the system by cables. An incoming call was
pre-announced by a throbbing pulse that so unnerved her she shut down the
system and wouldn't turn it on again.
The next day (she works at night) I "desensitized" her on this issue. ;-)
