Abstract

Verfahren zum Betrieb eines Hörhilfegerätes sowie Hörhilfegerät mit einem Mikrofonsystem, bei dem unterschiedliche Richtcharakteristiken einstellbar sindMethod for operating a hearing aid and hearing aid with a microphone system, in which different directional characteristics are adjustable

Bei einem Hörhilfegerät mit einem mehrere Mikrofone (1, 2, 3; 20; 30; 40) umfassenden Mikrofonsystem soll die Richtwirkung verbessert werden, ohne dass hierbei eine von einem Hörhilfegeräteträger als störend empfundene Zunahme des Mikrofonrauschens entsteht. Hierzu schlägt die Erfindung vor, dass die Einstellung des Mikrofonsystems statisch oder adaptiv unter Berücksichtigung der individuellen Ruhehörschwelle bzw. unter Berücksichtigung der individuellen Maskierungsschwelle für das von dem Mikrofonsystem erzeugte Mikrofonrauschen erfolgt. Somit kann stets das größtmögliche Maß an Richtwirkung zugelassen werden, ohne dass dabei der Hörhilfegeräteträger das von dem Mikrofonsystem erzeugte Mikrofonrauschen als störend empfindet.

Figure imgaf001
In a hearing aid device with a microphone system comprising a plurality of microphones (1, 2, 3, 20, 30, 40), the directivity is to be improved without an increase in the microphone noise perceived as disturbing by a hearing aid wearer. For this purpose, the invention proposes that the adjustment of the microphone system takes place statically or adaptively taking into account the individual rest hearing threshold or taking into account the individual masking threshold for the microphone noise generated by the microphone system. Thus, the greatest possible degree of directivity can always be allowed without the hearing aid wearer perceiving the microphone noise generated by the microphone system as disturbing.
