Actually starquad does help with regard to external noise.
It effectively decreases the loop area and subsequently the cable's inductance. The lower a cable's inductance, the less the magnetic field that it radiates and vice versa, the less susceptible it will be to external magnetic fields.
Electrostatic shielding doesn't help much with regard to magnetic field interference. The permeability of copper is about the same as that of air so in order for it to be effective at magnetic field shielding, it must be rather thick.
