• Low levels of ambient magnetic field are attained using a 5 layer Mumetal enclosure.
• Microphones may also be matched to their load with a small transformer, which is mumetal shielded to minimise noise pickup.
• A number of different proprietary formulations of the alloy are sold under trade names such as " MuMETAL ", " Mumetall ", and " Mumetal2 ".
