Abstract (en)
A hearing aid is provided comprising a magnetically sensitive transducer (11) for conversion of a varying magnetic field into an audio signal, a processor (16) configured to generate a hearing loss compensated output signal based on the audio signal, an output transducer (20) for conversion of the hearing loss compensated output signal to an auditory output signal that can be received by the human auditory system, an RF transceiver (22) for wireless communication, and a communication controller (24) that is configured to turn the RF transceiver (22) on and off, and wherein, the processor (16) is further configured to generate, within a time period (40) comprising the event that the RF transceiver (22) changes state between on and off, the hearing loss compensated output signal based on an estimate of the audio signal, and wherein the estimate is based on a part of the audio signal input to the processor (16) outside the time period (40), whereby possible interference from RF-transmission is removed from the audio signal.
