1. A hearing aid comprising:
a housing;
an input transducer for receiving an acoustic signal from a user's surroundings and providing a corresponding input audio signal and/or a receiver for electronically receiving an input audio signal;
a signal processing circuit for processing the input audio signal;
an RF antenna arranged in the housing, the RF antenna configured to receive and/or transmit electromagnetic RF signals within a first frequency range enclosing a first frequency of resonance of the RF antenna corresponding to a first wavelength;
a loudspeaker configured to be positioned in the ear canal of the user and to provide an audible signal to the user in dependence on the processed audio signal; and
one or more electric leads electrically connected to lead one or more electric signals within a second frequency range not overlapping the first frequency range between the loudspeaker in the ear canal of the user and an electronic circuit in the housing,
wherein the one or more electrical leads are decoupled, at a connector end of the one or more electrical leads, by means of one or more decoupling components.
