Abstract:
1. A hearing aid system comprising: a first hearing aid having a first microphone, a first acoustic output transducer, a first electronic receiver and a first processor, said first processor being adapted to process an output signal from the first microphone and an audio output signal from the first electronic receiver in order to output through the first output transducer an acoustic signal for a user's right ear, a second hearing aid having a second microphone, a second acoustic output transducer, a second electronic receiver and a second processor, said second processor being adapted to process an output signal from the second microphone and an audio output signal from the second electronic receiver in order to output through the second output transducer an acoustic signal for a user's left ear, an electronic transmitter system adapted to transmit an audio signal for being simultaneously received by said first and second electronic receivers, and means for selectively inverting the polarity of the audio signal of one of the first or second electronic receivers as compared to the polarity of the audio signal of the other one of the first or second electronic receivers.
