Cable Aluminium Foil
- Except for the outer jacket that protects against physical damage a cable also has a shielding for protection against external signal interferences. These interferences may corrupt data transfer or create unwanted noise in an audio signal. Different types of shielding are used, as they differ in their specific advantage in protecting signal frequencies.
- Aluminum foil shielding is ideal for reflecting electromagnetic interference (EMI) and is often used in combination with a braided wire to absorb EMI.
