The same logic can be applied to noise.Local noise created by appliances, power cords, [unshielded] wires or electronic components come from devices that are attached to AC power, which in turn are attached to [earth] ground. So noise can either go thru the component's power supply to complete its circuit, or it can go thru the ground by way of grounded side of AC.
Now, anytime a component that is properly grounded and shielded is subjected to noise, then ground offer a path to complete return path to noise signal to where it is was originated from. This way the noise signal doesn't have to go thru the components's power supply to complete its signal path.
So components that are grounded (preferably with a rod that is buried 8 feet in the ground) offer a "short" to noise signal to reach its destination, and in return are much quieter and have lower S/N ratio :)
