Alright. It's not just ground loops. Everyone who attribute electrical noise only to ground loops doesn't understand noise.
Ground loops matter, but the way the current and signal flow in the wire matters too. Ott's book pages 58 and 59 show 10 configurations, 5 ground loop configurations and five non-ground loop configurations, all with different noise suppression characteristics.
Cutting a ground loop will cut ground loop currents and the associated noise, but there's another 25db of noise suppression between the worst performing and best performing non-ground loop configuration.
The Wiki page is about ground loops, so talks about ground loops. That doesn't mean ground loops are the only consideration or even the most important consideration. If your problem is about noise in wires, then there's more to it than ground loops.
