Abstract
In a hearing aid device with an induction coil and a method for reducing magnetic noise fields, a compensation-inductance is arranged in the signal line of the earphone for the active shielding of the earphone, the compensation-inductance generating a compensation field that is directed opposite the magnetic field of the induction coil. The compensation field opposes the magnetic field of the earphone and creates an active shielding of the earphone during operation of the induction coil.
