A hearing aid is provided comprising a microphone, a signal processor for processing an incoming audio signal to compensate a hearing loss of a user of the hearing aid, a speaker that is connected to an output of the signal processor to provide a sound signal to a user, a transceiver connected to the signal processor for wireless data communication interconnected with an antenna for emission and reception of an electromagnetic field, an electrical circuitry comprising at least one of the signal processor, the transceiver, interconnecting transmission lines, antenna structures and/or further electrical components, the electrical circuitry extending over an area of a support substrate. The hearing aid further comprises a resonant element being provided within the near field of the electrical circuitry to terminate and dissipate unwanted electromagnetic radiation from at least a part of the area. The resonant element implements a notch filter filtering the unwanted electromagnetic radiation and may be positioned outside any signal paths of the electrical circuitry. |
