Hearing aid system, a hearing aid and a method for processing audio signals
First Claim
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 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 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 a signal for being received by said first and second electronic receivers, and means for inverting the polarity of the output signal of one of the first or second electronic receivers as compared to the polarity of the output signal of the other one of the first or second electronic receivers.

Abstract
A composite hearing aid system comprises two hearing aids (11, 31) with respective microphones (12, 32) and electronic receivers (17, 37), a microphone (42) and a transmitter (41) adapted to transmit the signal from the microphone (42) to the electronic receivers. At least one of the hearing aids (11, 31) comprises means for inverting the phase of the signal received by the electronic receivers (17, 37). When the phase of the received signal is inverted in one of the hearing aids (11, 31), a release from masking is obtained, and the perceived signal-to-noise ratio is improved. The invention provides a composite hearing aid system, a hearing aid and a method for processing audio signals.

- 10. A hearing aid comprising a microphone, an acoustic output transducer, a processor, and means for interfacing with an electronic receiver, said processor being adapted to process an output signal from the microphone and an output signal from the electronic receiver, said means for interfacing with the electronic receiver having means for inverting the phase of the output signal from the electronic receiver.
- 14. A method for processing an audio signal derived from a pair of audio sources associated with a pair of hearing aids, comprising inverting the phase of the output signal of one of the audio sources as compared to the phase of the output signal of the other one of the audio sources.
