<p>A hearing aid includes: a microphone for reception of sound and conversion of the received sound into a corresponding first audio signal; a signal processor for processing the first audio signal into a second audio signal compensating a hearing loss of a user; a speaker connected to an output of the signal processor for converting the second audio signal into an output sound signal; a transceiver connected to the signal processor for wireless data communication; and an antenna for emission and reception of an electromagnetic field, the antenna coupled with the transceiver; wherein the signal processor, the transceiver, the antenna, and interconnecting transmission lines form a circuitry extending over an area of a support substrate, and wherein the hearing aid further comprises a resonant element within a near field of the circuitry to terminate and dissipate unwanted electromagnetic radiation from at least a part of the area.</p> |
