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.
L'invention concerne un système d'appareil auditif composite comprenant deux appareils auditifs (11, 31) avec des microphones (12, 32) respectifs et des récepteurs électroniques (17, 37), un microphone (42) et un émetteur (41) adapté pour émettre le signal du microphone (42) aux récepteurs électroniques. Au moins un des appareils auditifs (11, 31) comprend des moyens d'inversion de la phase du signal reçu par les récepteurs électroniques (17, 37). Lorsque la phase du signal reçu est inversée dans un des appareils auditifs (11, 31), on supprime le masquage, et le rapport signal-bruit perçu est amélioré. L'invention concerne un système d'appareil auditif composite, un appareil auditif et un procédé de traitement de signaux audio.
