Abstract (en)
[origin: EP1748678A2] Hearing device comprises microphones (M1, M2) arranged in an earpiece which is symmetrical to a loudspeaker (LS), a microphone matching unit (MM) for adjusting the differences of the microphone signals and a signal processing unit (SA) connected to the microphone matching unit for processing only parts of the microphone signals to the loudspeaker. An independent claim is also included for a method for reducing feedback in the hearing device. Preferred Features: The device has an amplifier for amplifying an unpitched sound passing into the earpiece more than the unpitched sound coming from the loudspeaker.
