ABSTRACT:
A system providing hearing assistance to a user having a wireless remote control for transmitting control commands as an amplitude modulated radio frequency signal, an RF power detector for outputting a signal representative of the power envelope of the RF signal received by an antenna of the RF power detector, a classifier unit for analyzing the output signal of the RF power detector to detect control commands of the remote control and to detect the presence of a source of interfering RF signals, an audio signal processing unit, and a user's ear worn part for stimulating the user's hearing according to audio signals processed in the audio signal processing unit. The classifier unit provides a control signal representing detected remote control commands and an interference signal representing the presence of a source of interfering RF signals. Operation of the audio signal processing unit is controlled by the control signal.
