1. A multi-shelled shielded room, comprising:
an outer shell with a first soft magnetic alloy that has an initial permeability μi1 and a maximum permeability μmax1;
an inner shell with a second soft magnetic alloy that has an initial permeability μi2 and a maximum permeability μmax2;
wherein the outer shell encases the inner shell and μmax1>μmax2 and μi2>μi1; and
wherein the inner shell and the outer shell each comprise a base plate made of a vibration-damping material and at least one sheet layer made of the first alloy or the second alloy, respectively.
