Yes, someone supports me, ground-loops are 50 or 60 Hz in audio systems http://en.wikipedia.org/wiki/Ground_loop_(electricity)

Even a 50/60Hz hum from a classic ground loop has tons of loud harmonics reaching into the mid range.

Ground loop issues with computers show up as some strange digital noise (high- and whatnot-pitched) and not as mains hum for some reason, even though the culprit is basically the same.
