Mu-metal is effective at reducing induced noise in signal sensitive gear with high gain and small signal levels. If you are trying to achieve the quietness of state-of-the-art hifi, try enclosing transformers or other components with Mu-metal.
Circular layer (overlapping ends) around a transformer or other components. More wraps = more attenuation.
Best shielding is obtained by enclosing both the source and the device.
Edges will be sharp. Caution when handling.
It has an adhesive backing (picture shows front and back of one sheet).
