Abstract (en)
[origin: EP2375784A2] The hearing aid comprises a signal processing unit for processing a signal received from a signal recording unit. A magnetically operated loudspeaker unit is provided, which converts an output signal from the signal-processing unit into an output sound. A shielding unit (21) made of an amorphous, soft-magnetic metal is arranged between the loudspeaker unit and the signal processing unit for reducing electromagnetic interference on the signal processing unit by the loudspeaker unit.
