Abstract
For reducing the influence of interference fields on hearing aids, a hearing aid is provided with an electronic component into which a first and a second electromagnetic disturbance component can be injected by providing a predetermined electromagnetic interference field. The electrical component is formed asymmetric and/or a compensation component is arranged on the electrical component such that the first and the second interference components largely compensate for one another. A compensation plate or an element which is provided in any case, such as a microphone, may be used as the compensation component. If the electrical component is a coil, then its core may, for example, be conical or configured such that its winding density varies.
