Hearing aid and method for operating a hearing aid with a microphone system in which different directional characteristics are selectable

摘要

in a hu00f6rhilfegeru00e4t with a richtmikrofonsystem with at least three microphones (5, 6, 7, 20, 21, 22, 40, 41, 42) is the signalu00fcbertragungsverhalten are improved. the invention proposes several microphones, each microphone units to verschalten to, with the order of the directional characteristic of the microphone units respectively are identical.finally, the mikrofonsignale this microphone units are added, so that the order of the directional characteristic of the resulting mikrofonsystems the order of the directional characteristic of the individual microphone units.thereby, the microphone system according to the invention, the signalu00fcbertragungsverhalten compared to a single mikrofoneinheit improved, without it an increased mikrofonrauschen or a deterioration in the sound quality is generated.
