Double-shielding is the standard way of minimizing EMI (electromagnetic interference) and RFI (radio frequency interference). It consists of braided copper and a foil, generally aluminum or copper. The copper braided shield has been effectively proven to repel RFI and the foil shield repels against EMI. The actual amount of coverage by the braided or foil shield will determine how much interference is actually repelled.
Proper Shielding, Interrupted Noise Path
For Maximum performance, the shield is soldered (grounded) to the "source" end and is not soldered (un -grounded) on the "destination" end. This will ensure that any noise picked up by the shield will not transmitted into the signal path. This is why for AV cables the ends are not interchangeable, and cables are best connected one way, with the grounded shield towards the signal source.
